plane fire bullets
the way i want the code to work is to always fire the bullet up at a speed of -15 when the spacebar is pressed but after the first bullet, there are a ton of glitches and when u press the spacebar the bullet just moves in the direction that the plane is going and at the same speed. any suggestions or code changes will help. thx.
