What should I use as a key for a resource manager? Currently, I am using the filename as the map key. However how do resource manager handles resource like textures? The problem I have is a same texture(Texture-A), can be loaded with different parameters. e.g Step 1. ResMgr load Texture-A with mipmap. Step 2. ResMgr load Texture-A with colorkey. If I am to just use the filename as a Key for the resource manager, when I choose to load Texture-A the second time, it will signal that it was already loaded and return the texture. However the return texture is the wrongly created texture. How should I solve this? Should I make all possible parameters as a key instead?

When you load it with different parameters are you going to reload the file? Why not use an int. the resource manager could keep a static int and just one up it every time it needs a new key.
