Back to what I typed before the red x fiasco. The barriers would have to be higher than 2. The actual game uses pixel perfect collision and it takes several shots to get through it. I'm not looking for that much detail, but I want it to take several shots to get through it. I'm thinking 10x10 or something like that. There's going to be a problem with the collision, as it causes other sprites to move around. I say, create different layers. We don't want collisions with enemies and their own bullets, they will scatter. If say, the enemy layer is the same layer as my bullets. The enemies bullets would be the same layer as my ship and barriers. Then we would have to create 2 player bullets on each layer for each shot that travel together, one on the enemies layers and one on the barriers layer. They could be different colors and shapes. Maybe a blue teardrop shape bullet with a red circle in the middle of the teardrop shape. That way we can detect either collision, barrier or enemy, disintegrate the barrier or kill the enemy, delete both bullet sprites that represented that one bullet. What do you think?
