![[UPDATED] BatCave3D: techniques demo](https://cdn2.scratch.mit.edu/get_image/project/146240126_480x360.png)
UPDATE: Healthbar watcher was too long for Chromebooks, so made a healthbar using a sprite +clone. Also, gave bat some 'tilt', and timer display now uses clones and costumes for digits. I really liked the concept of @Doctor_Llama's original project. And, after helping eliminate some lag and layering issues (see https://scratch.mit.edu/discuss/topic/239984/ ), I tinkered around with it some more and saw an opportunity to demonstrate some useful techniques for doing certain things in Scratch. Here are some of them (loads of comments inside for more)... • One main loop sends 'tick' broadcast to control everything. • Rate of game-play constant (roughly) even as FPS changes. • Ramp-up of difficulty, and speed, as game progresses. • Clones behaving slightly differently depending on costume. • Overcoming Scratch's size and position limits on sprites. • Clones for digits of timer display, frugal costume changes. • Healthbar using sprite and clone. Lots more could be done with this (objects to pick up, levels, cloud high-scores, etc.), but hope there's some useful stuff here... :)
