You can view the source code here.

On this page, you'll find documentation on the main API that the SADX Mod Loader exports to every code based mod created for SADX. There are additional features which are documented on other pages. You can follow the below links to find documentation on those features.

Below is the initialized version of the HelperFunctions struct. For the definition of the struct, you can find that in SADXModInfo.h

  Please be aware that all examples on this page will be using helperFunctions which is how the variable is sent to a mod.

Properties

Mod Loader Version

int ModLoaderVer;

This returns the version of the mod loader. This can be used to check if the user has an old version of the mod loader that may not have functionality your mod requires.

Example

if (helperFunctions.ModLoaderVer <= 10)
    PrintDebug("This Mod Loader is way out of date.\n");

Mod Loader Settings

LoaderSettings loaderSettings;

Example

// TODO: Write example.

Mod List

std::vector<Mod> modlist;

Example

// TODO: Write example.

Weight Functions

BasicWeightFuncs weightFuncs;

Example

// TODO: Write example.

Functions

Register Start Position

static void RegisterStartPosition(unsigned char character, const StartPosition& position)

Registers a new Start Position for the specified character.

Example

StartPosition myStageStartPos = { 
    1,                          // Level ID 
    0,                          // Act ID
    { 100.0f, 200.0f, 100.0f }, // Position
    0                           // Y Rotation
};

// We pass our StagePosition variable as a pointer to this function
// and we have specified Sonic, so the level for this ID would now use
// our StartPosition instead of the original.
helperFunctions.RegisterStartPosition(Characters_Sonic, &myStageStartPos);

Clear Start Position List

static void ClearStartPositionList(unsigned char character)

Clears the Start Positions for the specified character.

Example

// Running this inside of your mod's Init export would
// clear all of Sonic's Start Positions for his stages.
helperFunctions.ClearStartPositionList(Characters_Sonic);
