Continuing my 194X experiment: Stealth Bullets

[selimanac]

Did you check the Z value of the bullets position?

Objects randomly disappear when running the game multiple times without any changes

It is probably because of a z-fighting issue. I bet all your game objects have the same Z value, so they are fighting each other. You might try changing them a little, something like: Background: Z = 0.0 Stars: Z = 0.1 Ship: Z = 0.2 This should help prevent z-fighting.
