Hey all!
Im quite new to unity and have question to you guys.
I want to controll the leg of a character by moving the joint of the foot with the cursor so that the lower and upper leg are transfromed relatively. A little bit like this one, but just with one leg.

Does anybody know how to achive that?
What you are showing is a sprite animation. This is the same concept as traditional animation in which each “frame” of animation is drawn and then swapped out to appear as though the character is moving. When you talk about moving a leg relative to a dynamic control you are likely not referring to a something that could be achieved with sprite based animation, but would probably necessitate what is called an IK rig which stands for Inverse Kinematic. I’m afraid that you have not provided enough information here to begin to understand what you are trying to achieve.
Although it may be hard to hear this you really just need to take a few months and follow the unity tutorials without any expectation of solving your particular problem, but just to gain enough knowledge to know what question you should be asking.
hey thanks for you answer! IK rigging is definitely the term i was searching for.
