This is a test to see if I can create a 3d engine for Scratch. The test looks very promising! Use forward and back arrow keys to move in 3d. When you move all the way back, the bat will fly after you in 3d. When you move one step forward, the bat will fly back to guard the door. Wherever you move, the bat changes size to stay in perspective. I hope to expand this to a full game soon... Hope the test is useful to you. 3D Tutorail at: https://www.youtube.com/watch?v=tYBHJ2XMpQo
