// test/render/feedback2-enemy-attack-clip.test.js — GitHub #58, client side: an enemy plays its attack clip once per
|
||
// attack at the clip's own speed (faster only when the attacks come quicker than the clip) and then its resting clip —
|
||
// Move while the sim walks it again (server/sim/ai.js attackStand stands it for exactly that clip). It used to stretch
|
||
// the clip over the whole attack interval and loop it for 1.4 intervals, so a ranged enemy seemed to slide while it
|
||
// attacked. Operators keep the clip looping over their attack rhythm. Headless fake PIXI (test/render/fakepixi.js).
