KinematicBody - friction

Berfandil

Hey all!I made a character as a KinematicBody and started moving around with it.When I collided with a wall, I tought at first: "OK, I stopped, this is how collision should work, for I cannot go through a wall..."But then I turned a bit, thinking that I will slide slowly along the wall, but nothing happened.So I turned even more, but no movement happened, until I was facing a direction parallel with the wall.So, what causes this behaviour? How could I tell my character to start sliding?

Hello BerfandilIf I'm not mistaken, you only use the code [code]move(velocitydelta)[/code]What it does is to move the body until there's a collision. But it doesn't make the body slide. Therefore you get stuck when you touch a wall. You have to script that too, with the method slide of a vector (which is the normal of the wall you're sliding against. Your code should look like:[code]var motion=velocitydeltamove(motion)var original_vel=velocityif is_colliding(): var n=get_collision_normal() motion=n.slide(motion) velocity=n.slide(velocity) # check that the resulting velocity is not opposite to the original velocity, which would mean moving backward. if(original_vel.dot(velocity)>0): motion=move(motion)[/code]And then you can slide.

Thank You very much for your help! :)
