Resources you need:

• A spritesheet that contains your new sprites for the health icons. You can see an example spritesheet in the 'examples' directory of this mod. The example spritesheet has the sprite boundaries for the hearts color coded in red and blue for ease of use.
  
• An anm2 file that parses your spritesheet. This anm2 file MUST use the same animation names as the anm2 files currently in this mod (i.e. "Lost_Heart", "Lost_Dead", etc.). You can find an example anm2 file in the 'examples' directory.

Function to use: VLH.SetIconFilepath(filepath, modName)
@param filepath (string) The filepath to your anm2 file for your new sprites, starting at the Repentance mods directory.
@param modName (string) Optional. The name of your mod; this will overwrite "CUSTOM" in MCM settings.

You can also find a psd file in the 'examples' directory that includes the sprite artwork for the current hearts, if you want to use that as a starting point for your own sprites.

Hey. I did everything that i must, but my sprites isn't working.
It shows normal hearts instead of mine.
