I am trying to replicate Celeste's engine. 60 fps: turbowarp.org/992055612?fps=60 60 fps and true size (use fullscreen addon): turbowarp.org/992055612?fps=60&size=320x180 Controls: Left-Right arrows: move Down arrow: duck Z: climb X: dash (not implemented) C: jump As of now: Collisions do work. Texture and hitboxes use a caching system to run faster The texture and hitboxes are still the most expensive tasks TODO: 1. Coyote time 2. Climb hop 3. Jump and unduck x alignment when hitting the ceiling 4. Sliding down a wall 5. Stamina 6. Jump off of a wall while holding a key should give you air friction of 260 for some reason, I can't find this on the source, but it happens on Celeste somehow - beta 2
