Question on making an actor "jump"
I am currently trying very desperately to make something work in my game. Here goes: I want to have an actor change its speed to say, 300 (it has to change directly to that amount and not accelerate, otherwise i would have used the accelerate towards behavior) , whenever i touch the screen, and make it to travel towards wherever i pressed. When it has that speed (of 300) and direction (toward where ever i pressed) i want it to slow down by setting the drag to say, 100. The problem here is, that i dont know what formula to use for the linear velocity x and y. I will be sooo grateful if someone will solve this for me. Thank you for your time
