READ INSTRUCTIONS!!! This is a basic birds eye view collision engine you can use in your games. All you have to do is put the "run sensor" block at the bottom of your script and It will give you black things collision. See inside for more details. There is also a block that gives you both the sensor engine and smooth movement called "movement engine" (you can adjust the speed). Arrow keys to move in this sample. If you want to try pushing the cube using this engine, go into turbo mode (shift and click green flag at same time) and grab the big box with your mouse. Push the cube around.
Credits to ME! (made it all by myself) I made another engine, (with a few tweaks) and the test map is a MAZE! :D http://scratch.mit.edu/projects/19538720/
