speykious / inochi2d-c

A layer for using Inochi2D with non-D programming languages via a C ABI

Inochi2D SDK for C ABIs

This repository contains the neccesary code to use the reference Inochi2D implementation outside of DLang, as well as with non-Inochi2D renderers.

Initializing and Closing Inochi2D

You will need to pass a function with the signature double timingFunc() to Inochi2D on initialization.

• timingFunc should return the current time of the application rendering the game in sec.ms format.
• timingFunc is used for physics as well animation calculations

double timingFunc() {
    return glfwGetTime();
}

To initialize Inochi2D itself you will need to call inInit passing your timing function in.
Remember to run inCleanup when you're done using Inochi2D to unload the DLang runtime!

inInit(&timingFunc);
    // Game and Inochi2D goodness happens here
inCleanup();

Loading a puppet

Use inLoadPuppet to load a puppet, you will need to pass an UTF-8 encoded null-terminated string to this function.
Use inDestroyPuppet to destroy a puppet when it no longer is needed.

    InPuppet* puppet = inLoadPuppet("myPuppet.inp");
    // Do stuff

    inDestroyPuppet(puppet);

Using Inochi2D with your own renderer

Inochi2D requires the following GPU accellerated features to be present:

• Framebuffer support (Inochi2D needs 2)
• sRGB->Linear RGB conversion support
• Premultiplied Alpha support
• Vertex buffers
• Stencil buffers
• Pixel shaders
• ROP support or method to emulate porter-duff blending in shader
• At least 4096x4096 texture resolution support

Optionally the following features may be present

• SPIR-v shader support (For per-part shaders)
