Custom sounds and music are common in SRB2 addons. This tutorial teaches you how to add them to WAD or PK3 files. If you want custom music to be played in your custom level, see the level header article.

Sonic Robo Blast 2 is a 3D open-source Sonic the Hedgehog fangame built using a modified version of the Doom Legacy port of Doom.SRB2 is closely inspired by the original Sonic games from the Sega Genesis, and attempts to recreate the design in 3D. Originally based on the Mario Kart mode of SRB2 Riders, it is a kart racing game with Sonic and SEGA-themed characters, items and maps. A while back Bethesda took the Unity ports of Doom and Doom 2 made for consoles and added them to the Bethesda launcher, making the 90s shooters run at 60fps with widescreen support and an add-ons. My first release for SRB2 Kart Emerald Lake is based on the Project RoboTower stage of the Same name. This stage is basic, but as my first kart track, I believe Basic is good. The track features a tunnel, a water segment, and a segment of the SP stage as scenery. The whole track can even be completed in under 3 min.

Accepted sound formats

SRB2 v2.2 can play many different sound and music formats. Like Doom itself and Doom-based games and mods, SRB2 includes native support for the Doom Sound Format, though another widely used format for sounds is WAV (.wav). The most widely used format for music is Ogg Vorbis (.ogg), as it compresses well without much drop in quality.

Below is a list of the formats supported by each of the sound/music libraries included with SRB2.

Required tools

• Your sound or music file, which can be in any of the supported formats listed above. If your file is in an unsupported format, you need to convert it using additional software such as Audacity.
• A lump editor. SLADE is recommended for this, but this tutorial will also cover XWE where necessary.
• If you want to add a loop point to your music, you also need a media application capable of editing a file's information tags, such as Audacity.

Sounds

File format

You can use any of the supported formats listed above for your sound file. However, some MP3s may not work properly as sounds (though they may work fine as music). Since sounds are usually short, you can safely use uncompressed formats such as WAV.

Choosing the lump name

Before you import your sound lump, you need to know how to name it. The names of sound lumps are prefixed by DS, e.g., DSSPIN. If you want to replace an existing sound, look up the name of the lump in question in the list of sounds and give your lump the same name. To find out which sounds you want to replace, you can preview SRB2's sound lumps, which are stored in the file srb2.pk3. SLADE and XWE both have settings for filtering the lump list, by selecting 'Audio' on the 'Show' drop-down box, or with the 'Sound' button, respectively. Now that only sound effect and music files are shown, select the sound effect you want to check from the list and click the play button, or if using XWE, select Wave → Play in the menu bar.

If you want to add a new sound without replacing an old one, you must declare a name for it via SOC or Lua. The game will then automatically reserve one of 1600 free slots for the new sound. The internal sound names used by SRB2 are in lowercase and use a sfx_ prefix. For example, if the name of your sound lump is DSCUSTOM, you must declare the sound as sfx_custom. See Freeslot > Declaring freeslot names for a guide on how to declare custom sounds.

Importing the sound file

Now you can import your sound file into your WAD or PK3 file as a lump. Open the WAD or PK3 file with your lump editor. Now insert your sound file. In SLADE, you can simply drag and drop the file into the lump list. In XWE, select Entry → Load on the menu bar, navigate to the folder that contains your file and insert it. Once the file is imported, make sure the lump name matches the name you decided to use. If not, right-click on the lump and select Rename or Rename Entry, respectively.

Now save the WAD or PK3 file, close the lump editor (XWE saves automatically) and load the file in SRB2 for testing. If the sound isn't played, check if you gave your lump the correct name and, if necessary, declared the freeslot correctly.

Music

File format

Unlike sounds, music files are typically fairly long, so you should make sure the size of your file isn't too large. This isn't a problem with sampled music in the MIDI and MOD formats, whose file size is already very small. Recorded music (formats like MP3 and Ogg), however, can become rather large when using a high bitrate. It is recommended that you use the Ogg format (which sounds better at low bitrates) with a bitrate of no more than 128 kb/s. This article will not cover how to convert to Ogg. Note that if you choose to use the Ogg format, your file must have a sampling rate of 44,100 Hz to function properly.

Choosing the lump name

Before you import your music lump, you need to know how to name it. Most music lumps in SRB2 go by the naming convention O_MAPxxM, with xx being the two-digit form of the number of the map in which the music should be used; for map numbers above 99, extended map numbers must be used. Some music lumps that are used for special purposes in the game don't follow this convention, such as O_CHRSEL for the music on the character select screen. If you want to replace SRB2's own music, look up the name of the lump in question in the List of music article and give your lump the same name. For example, if you want to replace the music for Greenflower Zone Act 1, name your lump O_GFZ1. If you don't want to replace existing music, you can give the lump any name as long as it starts with O_.

Note that music lumps in the MIDI format start with the prefix D_. The prefix O_ is used for all other formats.

To find out which music you want to replace, you can preview SRB2's music lumps, which are stored in the file music.dta. SLADE can play back Ogg music itself, but if you're using XWE, you will need to export the file. To do this, select the music lump in question and select Entry → Save As... in the menu bar. If your music lump starts with O_, you must save it as an Ogg file. Under 'Save as type', select 'All Files (*.*)' and then save your file as filename.ogg. Don't forget the file ending .ogg or your music file cannot be opened. After saving the file, you can open it in a compatible music player.

Looping (optional)

For digital music formats that do not automatically loop, there is a way to supply an external looping point for the music. This will cause SRB2 to loop the music back to a predefined point once it finishes playing, rather than the beginning of the track.

There are three ways to set up a loop point. The first two involve using a dedicated metadata tag, while the last uses the file's COMMENT metadata field.

The preferred way of setting a loop point is using the LOOPMS metadata tag. When using LOOPMS, the loop point should be supplied in terms of milliseconds. Audacity can insert this dedicated tag in the 'Export' dialog. To do so, click 'File' on the menu bar, click 'Export', and select your preferred audio format. Then, after selecting the folder you want the audio file to be exported to, click the 'New' button in the 'Edit Metadata Tags' window. Input LOOPMS as the name for the tag and input the desired time in milliseconds as the value (for example, 30.25 seconds equal 30250 milliseconds).

The other methods require that you supply the loop point in terms of audio samples, directly related to the sampling rate of the file. A crude way to calculate the value of the loop point would be to multiply the position where you want to place the loop point, in seconds, with the sampling rate of the file – for example, to place the loop point for a file with a sampling rate of 44,100 Hz at 30.250 seconds, you would use 1334025 (= 30.25 × 44100) as the value. A more fine-grained method is to load the file in Audacity, identify the best position for the loop and then look up the precise sample number at which it occurs.

The second method of setting a loop point is through another dedicated metadata tag, the LOOPPOINT tag. You can add this tag the exact same way as the LOOPMS tag; just use LOOPPOINT as the name instead, and the number of samples as the value (1334025 with our example).

The third and last method of supplying a loop point is to insert the text LOOPPOINT=<value> in the COMMENTS field of the music file, where <value> is the number of audio samples as mentioned above (again, 1334025 with our example). This method for providing a loop point is deprecated and exists only for backwards compatibility with older versions.

Note that music modules and emulated music tracks use different built-in mechanics for looping the track – if you need to edit the loop point for such a track, you should consult a tutorial for the format in question. MIDI tracks cannot be looped in SRB2 at all.

Importing the music file

Now you can import your music file into your WAD or PK3 file as a lump. Open the WAD or PK3 file with your lump editor. Now insert your music file. In SLADE, you can simply drag and drop the file into the lump list. In XWE, select Entry → Load on the menu bar, navigate to the folder that contains your file and insert it. Once the file is imported, make sure the lump name matches the name you decided to use. If not, right-click on the lump and select Rename or Rename Entry, respectively.

Now save the WAD or PK3 file, close the lump editor (XWE saves automatically) and load your file in SRB2 to test the music. If the music isn't played, check if you gave your lump the correct name.

Listening to music with SLADE

SLADE can play certain sound formats, such as Ogg, MP3, WAV, and MIDI. Some other formats, such as VGM, cannot be played in SLADE and will appear as a lump of unknown type. This does not mean your VGM won't work, but be sure to add the file you're working on to SRB2 and test to see if the music works properly.

Sonic Robo Blast 2 Kart (usually shortened to SRB2Kart or SRB2K) is a source codemodification of Version 2.1 made by Kart Krew. Originally based on the Mario Kart mode of SRB2 Riders, it is a kart racing game with Sonic and SEGA-themed characters, items and maps. SRB2Kart features over 100 maps for two game modes: the main Race mode and a Battle mode where players fight each other using the items available in the game. Despite Version 2.2 being out, SRB2Kart is still supported by Kart Krew, the Message Board, and the Master Server. Future releases are still planned.

Gameplay and content

Srb2 Kart Track Addons Download

SRB2Kart's gameplay is that of a typical kart racer, with the ability to drift and get boosts from drifts, items to help or hinder the player, and many other staples associated with the genre. However, its handling and physics are different from other kart racers, with a focus on momentum and skill-based gameplay. Among differences, SRB2Kart introduces some new mechanics and techniques, including the sliptide (performed by turning inwards after receiving a boost), the Drop Dash (performed by holding Accelerate while respawning), and the ability to skip on water up to two times with enough momentum. In addition, items thrown behind the player will move drastically slower than if the player had thrown them forward, and certain items (Bananas, Eggman Monitors, and Mines) can be dragged behind the player as a means of defense, though this will cause them to slow down after a short time.

As of the current release, Single Player only offers a Time Attack mode where the player races against staff ghosts and earns medals for completing a course under certain times: Silver medals are awarded for beating a course's best time, and Gold medals are awarded by beating the top staff ghost of that course. Getting certain amounts of medals or playing a set number of races will unlock extra content, including additional cups and a harder race speed. Time Attack mode can't be played in a cheated game or if any major add-ons (i.e. different mechanics, extra game modes, level replacements or a character with an additional Lua script) are loaded.

The principal feature of SRB2Kart is Multiplayer, which can be played offline through local play with up to four players, or online through LAN or Internet with support for up to 16 players. Split-screen mode is supported for both online and offline modes, with up to four players on each client. If an online server requires certain add-ons, the game will download and load them prior to a join request, if the server allows file downloading.

Items

Items are provided by item boxes, which are littered across a track or battle arena. There are 16 different items which can be obtained:

Characters

See also: SRB2Kart/Character WAD

See also: SRB2Kart/Chart of characters

SRB2Kart features 5 characters available in the base game, as well as an additional 30 in the included optional bonuschars.kart add-on. Up to 128 characters (including the base game characters) can be added to the game at once through the use of add-ons. Characters are automatically balanced according to two stats with values between 1 and 9: speed and weight. A high speed stat lets the player reach faster speeds at the expense of worse acceleration, and a high weight stat makes it easier for the player to push others around with less handling and wider drifts as a trade-off. In addition, a character's speed and weight will directly affect how fast they build up drift sparks: a slower, heavier character (i.e. Dr. Eggman) will build up drift sparks much quicker than a faster, lighter character (i.e. Sonic).

Levels

Currently, there are 108 levels in SRB2 Kart, consisting of 12 Race cups with 5 tracks per cup for a total of 60 Race tracks (of which 3 cups/15 tracks are unlockable), 29 Battle arenas, 15 Map Hell Race tracks, 3 Map Hell Battle arenas and the Podium Evaluation map (which will be used in a future update).

Actions

Linedef flags

• Linedef flag 15: Invert Encore Remap – Inverts the effects of the Encore Remap if an Encore Palette has been made. With FOFs, this needs to be set on the linedefs in the map, instead of the ones on the control sector.

Linedef types

• Linedef type 323: Record Attack Load – A type of linedef executor trigger which activates any linedef executor within its control sector immediately after the level loads in record attack. This linedef executor only triggers once, and will not trigger again until the level is reloaded. The tag given to this linedef is irrelevant.
• Linedef type 328: Encore Load – A type of linedef executor trigger which activates any linedef executor within its control sector immediately after the level loads in encore mode. This linedef executor only triggers once, and will not trigger again until the level is reloaded. The tag given to this linedef is irrelevant.
• Linedef type 413: Change Music – Has the same functionality, but checking Flag [8] / Peg Midtexture / Effect 3 hides the music credit which shows whenever a new song plays.

Sector types

• Sector type 2: Offroad (Weak) – Slows the player down slightly unless they are under the effect of a speed boost.
• Sector type 3: Offroad – Slows the player down moderately unless they are under the effect of a speed boost.
• Sector type 4: Offroad (Strong) – Slows the player down greatly unless they are under the effect of a speed boost.
• Sector type 12: Wall Sector
• Sector type 112: Trigger Linedef Executor (Race Lap) – Activates the tagged trigger linedef on a certain lap of a race. The lap to use is based off of the player with the lowest current lap, unless Solid Midtexture is checked, in which case the lap of the player that enters the sector is used instead. By default the trigger linedef will activate if the used lap is equal to the front sidedef's x offset with an offset of 1 representing the second lap. If flags [6] / Not Climbable or [1] / Block Enemies are checked on the trigger linedef then the used lap must be greater than or equal or less than or equal to the front sidedef's x offset, respectively.
• Sector type 192: Invert Encore Remap – Inverts the effects of the Encore Remap if an Encore Palette has been made. Normally, everything is remapped barring Spring Panels and Sneaker Panels.
• Sector type 256: Spring Panel – Makes the player bounce forward after touching the sector like a spring, keeping any previous momentum or speed (or giving some if you didn't have too much speed).
• Sector type 768: Spring Panel (Speed Capped) – Makes the player bounce forward after touching the sector like a spring, but caps your speed to a certain amount during the jump instead of keeping it.
• Sector type 24576: Sneaker Panel – A boost panel, gives the player a speed boost upon contact.
• Sector type 40960: Circuit Finish Line – Marks the completion of a lap after crossing all checkpoints before it. Note that it can be used as a Section completion marker in case your track is a one-way/section race (laps used as sections).

Level header parameters

SectionRace

Default setting: false

This parameter is used to indicate if a track is a sprint race where there's a defined end. If this is set to true, then the number of 'laps' which the player would have to do will be no more than the NumLaps value given.

MobjScale

Default setting:FRACUNIT

This parameter is used to set the scale of all Objects in the map, in multiples of FRACUNIT.

Example:MobjScale = FRACUNIT/2 would scale all Objects in the map to half of its current size.

ZoneTitle

Default setting: (none)

Replaces 'Zone' with the title on this parameter, unless the NoZone parameter is set to true, in which case it won't display at all. The zone title is limited to 21 characters; if it is longer, a warning will be displayed and the name will be truncated to fit.
