Hi @RobyDX ! I just wanted to ask you for something,I'm quite new to SharpDX,I've been learning XNA,but I want to learn SharpDX.I've noticed that it's pretty similar, but I want to know how to detect mouse click or mouse over on the Texture2D,but I can't find anything in the Internet (I'm using the SharpDX Toolkit and Game class),can you help me? Regards!

Hi, collision detection (2D or 3D) can be detected in many ways. One example for 2D items is to get mouse position from form, get pixels from the texture and check if alpha is 0 (transparent) or 1 (opaque). Of course you must compute the position of the pixel based on texture position. Collision detection are part of a game engine and depend on your needs
