- HOW TO PLAY - Clikc the green flag and use the mouse to move your ship, and click the mouse button to shoot. You can only fire 1 shot at a time. - PROGRAMMER'S NOTES - I used 3 global variables, 2 to decide whether the two ships have shot or not, and the last one as the lives/health for the ship. To make the enemy ship explode, I added a bunch of costumes of an explosion animation broken down into still images, and then I had the ship change costumes, with a waiting period of 0.1 seconds between each costume change. Simple yet effective. - OTHER NOTES - This is the first project I've made with Scratch, so I think it's pretty good considering it's me just joking around with the systems.
