Collada Importer For GMS 2

*.dae (Collada) importer for game maker studio 2

Guys! Wanna support my work or me so i can do more cool stuff that could help you some day? https://marketplace.yoyogames.com/assets/7740/colladaloader

WARNING THIS LOADER DOESN'T CLEAN UP ANYTHING YET! USE AT YOUR OWN RISK!

WARNING: TO ENABLE MODEL CACHING REMOVE false IN ColladaLoad at line ~8

if( file_exists(fn1) && file_exists(fn2) && false )

replace it with

if( file_exists(fn1) && file_exists(fn2) )

Example

Usage:

0. Add it somewhere

#macro MatrixIdentity matrix_set(matrix_world, matrix_build_identity());

1. Import Collada scripts from ColladaLoader folder
2. Go to your object that will hold model and add this

model = ColladaLoad("model", false);
fSize = 100;

This will load "model.dae" realative to the exe false - is for animations which aren't working yet

3. In object's draw event add:

shader_set(shRenderColladaModel);
   //matrix_add_scale(fSize, fSize, fSize); // This can be also imported from this project
   // instead you can use matrix_set(matrix_world, matrix_build(0, 0, 0, 0, 0, 0, fSize, fSize, fSize));
   // Where fSize is value, i use 100
       // Load texture for model
       // model[1] - list of textures with following struct:
       var a = ds_list_find_value(model[1], 0); // [type, id]
       // Type:
       //    2 - surface
       //    1 - sprite
       
       // model[0] - final vertex buffer for loaded model with auto generated format
       var t = (a[0] == 2) ? surface_get_texture(a[1]) : sprite_get_texture(a[1], 0);
       vertex_submit(model[0], pr_trianglelist, t);
   MatrixIdentity; // Reset world transformations
shader_reset();

To enable debug messages replace false with true in following macro

#macro ColladaShowMessages false

---

P.S. Whanna work with animations? Add this thing somewhere:

#macro GetMaxWeightsSize 3
#macro GetMaxWeightsFormat vertex_type_float3

• You can change 3 and float3 to max number of joints that will affect vertecies
• Don't forget to do same thing in vertex shader of shRenderColladaModel
• Change 3 to same N of affecting joints #define MAX_JOINTS 3

Next:

Uncomment this in vertex shader:

GETFORMAT(MAX_JOINTS) Indices : TEXCOORD1;
GETFORMAT(MAX_JOINTS) Weights : TEXCOORD2;

and this:

    float4 TotalPos = 0.;
    
    for( int i = 0; i < MAX_JOINTS; i++ ) {
        TotalPos += mul(_Transforms[int(In.Indices[i])], In.Position) * In.Weights[i];
        
        // Same for normals
    }

Replace In.Position in

Out.Position = mul(gm_Matrices[MATRIX_WORLD_VIEW_PROJECTION], In.Position);

with TotalPos Enable animations in model loading:

ColladaLoad(model filename, true);

Add animation timer

fAnimTime = 0; // Required for animations

Add

ColladaAnimation(model, is loop animation);

to draw event after shader_set(shader id);

And have fun playing with ColladaAnimation script :P
