Aiming/Throwing mechanism in a 2.5D sidescroller

Hello,

I’ve been making a game similar to a game FEZ. I have made the camera and movement and now I want to make a throw mechanism. The problem is, I have watched a tutorials, asked an AI and other things to make it, but I’m new to this and I don’t know what I’m doing wrong or am I doing it in the correct method.

I want my character to throw on a direction where my mouse is aiming, but I couldn’t make it to every rotated angle my character/camera is facing(0°, 90°, 180°, 270°). It either throws on a fixed angle or throws it anywhere.

I’d appreciate any kind of advice, guide or steps.

Thank you.
