Shade

A small wrapper for gamemaker that makes shaders faster to use, especially uniforms and their typical long function names and use of multiple events

---

Setting up

Once you have imported the .yymps into your project using Shade is as simple as 3 lines.

if(!myShade) myShade = Shade(* shader asset *);
  
myShade.set();
  
  * draw *
   
myShade.reset();

This is the same as using shader_set() and then using shader_reset(), nothing much different. The cool part comes with uniforms!

Uniforms

Every Shade element stores a list of uniform ids, and you have full control on which are loaded with loadUni(* uniform name *), to apply a value to an uniform, you then use applyUni(* uniform name *, * value *, [variable type])

myShade.loadUni("u_time");

myShade.applyUni("u_time", current_time, UniTypes.f);

loadUni() is not necessary since applyUni() will load the uniform id if it wasn't loeaded before, but you can use it if you want.

UniTypes list

• f - float
• f_array - float array
• i - int
• i_array - int array
• matrix - transform matrix
• matrix_array - transform matrix array

Samplers

Samplers / textures work the same way as uniforms, but instead use loadSampler(* sampler name *) and applyTexture(* sampler name *, * texture *)

myShade.loadSampler("s_grass");

myShade.applyTexture("s_grass", sprite_get_texture(spr_grass,0) );
