Hello,

I'm trying to code a jump for my indie, but I'm having issues.

At first, I made a code that made the jump would be triangular. (meaning, jump -> reached max jump -> go down at same rate, it was visually like a triangle which I didn't like)

I want it to go as smooth as an hyperbole or demi-circle.

So I've changed the system used and implemented the following (C#):

public float updateJump(int j_state, float v_y)
        {

            float n = Math.Abs((float)Math.Sin(frametime * (Math.PI / 180d)) * JUMP_SPEED);

            switch (j_state)
            {
                case 0: // Not Jumping
                    frametime = 0;
                    break;
                    
                case 1: // Jumping Up
                    v_y -= n;
                    v_jump += n;
                    break;

                case 2: // Going Down
                    v_y += n;
                    v_jump -= n;
                    break;
            }

            if (v_jump < 0)
            {
                isjumping = false;
                v_jump = 0;
            }

            frametime++;
            
            return v_y;
        }

The thing is that it's doing it instantaneously or not even doing it, not sure if it's because funcs calls are too fast or some code error.

Thanks in advance.
