How to write a funtion with input is 2 TextureMaper, and output is check the collision between them.

[DNguy.14]

Hi everyone, I'm doing a game project with ST32 and ToughGFX for my Embedding Course. It's my first time using both, and I'm quite unfamiliar with the data struct in ToughGFX. Now I'm trying to write a funtion with input is 2 TextureMaper, and want to check the collision between them. Anyone can help me, I can't find any documents about this. 

Thanks you!!!!
