glsl spritesheet helper

spritesheet.glsl

// A helper to sample a section of a texture. useful for things like spritesheets.
// texCoord - uvs of the surface you're rendering to 
// imageSize - the size of the patch you want to sample 
// fulLTextureSize - the full dimensions of the texture you're sampling from 
// imageCoord - the x/y value of the section to sample from. 

// Sourced from @Gabor on Disccord in the @creativecode server. 
vec2 sample_section(
    vec2 texCoord,
    vec2 imageSize,
    vec2 fullTextureSize,
    vec2 imageCoord
){
   return imageCoord / fullTextureSize + imageSize * texCoord / fullTextureSize;
}

Another user named Simon suggested the following as well

color = texture( uSampler, uTextureParams[texId].xy + uTextureParams[texId].zw * normalizedUvs )

where in uTextureParams, xy is the translation and zw is the scale, though I haven't gotten this to work yet as I didn't ask for clarification on what he meant by normalizedUvs(as uvs are normally already normalized)
