GetEntityIndex()

[SpiderPig]

Similar to what I mentioned here for materials.  If I can get the index of an entity I can store extra data in a texture per entity.

Unless there's already a way to do this?

What i have found, is that the IDs are stored in the Render... classes, RenderMaterial, RenderTexture, etc. . These are all stored in private properties. There is a hackish way to access them (creating a separate class and modifying the original headers) but with every update this will be overwritten.

I would like to add also Texture ID access, which might be useful for PostEffects. 

Maybe some static class extensions for the IDSystem like

IDSystem::GetMaterialID(mat) 

IDSystem::GetTextureID(tex)

...

This is the hacky way without direct header access, but which needs to be updated when the class structure changes:

struct PublicMaterial : public Asset
{
    // copy everything from Material.h Material class here
	// remove the access modifier
	// remove all methods/constructors and friend functions
};

// Call this in your loop
auto refmat = (*sample_material);
auto mat = reinterpret_cast<PublicMaterial*>(&refmat);
auto materialId = mat->rendermaterial->id;

Regarding your latest update @Josh Does the entities index change through out the program or is it set once and that it until it's deleted?

[Josh]

it won’t change once it is assigned but it may not be assigned right away.

Your code should handle the case whdd Ed n it returns -1. Pivots and as my other nonvvisible will return -1

Perfect, thanks! Will put this to good use.
