Use this to make a game or something. Click "See Inside" and, in the "data control" sprite, attach the "START IN EDITOR" block to the "When flag is clicked" block and click the flag in order to access editor mode. In editor mode, use WASD to scroll, and press the spacebar to place objects. Use the "1" and "2" keys to control the ID of the object, and the "3" and "4" keys to control its texture. While not in the editor, you can click to shoot projectiles and press SPACE to swing a sword.
This is another rewrite of my scrolling engine, now with infinite tiles and a new physics system! Thanks to @TheLogFather for his tri-filler! ~Still kinda buggy, so please tell me about any bugs! ~There are still tons of things I'm working on, such as having triangular hitboxes in order to have slopes, and cool new pen-based effects that aren't possible using clones! -10/7/2019 New update you guys! @TheLogFather 's tri-filler allowed me to make some stellar parallax effects, and will allow for some crazy 3D effects! Collision detection got reworked, and the play area is now a bit less cluttered with debug information. -1/8/2020 Mostly optimized the parallax because I found it was pretty tough for lower-end hardware. Fixed some bugs in data loading and physics. Added enemies, cool explosions, projectiles, and a sword. Still working on that other stuff, though.
