Collada Importer For GMS 2
*.dae (Collada) importer for game maker studio 2
WARNING THIS LOADER DOESN'T CLEAN UP ANYTHING YET! USE AT YOUR OWN RISK!
Usage:
0) Add it somewhere
#macro MatrixIdentity matrix_set(matrix_world, matrix_build_identity());
- Import Collada scripts from ColladaLoader folder
- 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
- 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
// other - 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
- #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
