combatcactus could you possibly put that in code format

Edit: i have kinda fixed it when i press space and enter the jumping statement my yVel goes from 0 to -120 and moves -120 y's but then it changes back to 0 so he dosent come down. Here is my updated code

if (jumping == true){myDot.yVel -= 120;if (myDot.yVel <= -240){myDot.yVel += 240;jumping = false;}}
Following each iteration through there, it looks to me like this:
1. yVel gets -= 120, and should now be -120 (assuming you set it to 0 when jumping)
2. yVel <= -240 evalutes to false, code moves to next loop
3. yVel gets -= 120, and should now be -240
4. yVel <= -240 evaluates to True - you enter the if statement
5. yVel gets += 240 - and now becomes 0
6. jumping is set to false, nothing more is executed in that part

If you want to set your velocity to some downward velocity (like positive 240) once it reaches a maximum, you should do two things:
a) make the statement yVel += 240 be just yVel = 240;
b) make the check yVel <= 240 be yVel < 240
- doing these will results in your yVel being -120, -240, 0 (after each execution of your loop).
Hope that helps, because I'm still not 100% clear on how you're using your yVel.
