HelperFunctions API

Struct

Below is the initialized version of the HelperFunctions struct. For the definition of the struct, you can find that in SA2ModInfo.h

HelperFunctions

HelperFunctions helperFunctions = 
{
    ModLoaderVer,
    RegisterStartPosition,
    ClearStartPositionList,
    Register2PIntroPosition,
    Clear2PIntroPositionList,
    GetMainSavePath,
    GetChaoSavePath,
    RegisterEndPosition,
    ClearEndPositionList,

};

  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 Usage

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    PrintDebug("This Mod Loader is way out of date.\n");

Mod Loader Settings

LoaderSettings loaderSettings;

Example Usage

// TODO: Add proper example.

Mod List

std::vector<Mod> modlist;

Example Usage

// TODO: Add proper example.

Functions

Register Start Position

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

Registers a Start Position for the specified character.

Example Usage

// This is a declaration of an SA2 StartPosition struct.
StartPosition myStageStartPos = { 
    1,                          // Level ID
    0x4000,                     // Single Player Y Rotation 
    0x4000,                     // Multiplayer, Player 1 Y Rotation
    0x4000,                     // Multiplayer, Player 2 Y Rotation
    { 100.0f, 200.0f, 100.0f }, // Single Player Start Position
    { 90.0f, 200.0f, 100.0f },  // Multiplayer, Player 1 Start Position
    { 110.0f, 200.0f, 100.0f }  // Multiplayer, Player 2 Start Position
};

// 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);
