- With events.tricks a plugin hears the local skater's tricks: trick_started (where), trick_landed (points, multiplier, where it started and landed, how long it took) and line_broken (a slam or a wipeout); reskate.score.current() is the score HUD's line, multiplier and whether a trick is going on. Without the permission the events cannot be registered. - The score HUD is read into the trick watch (Extension/Skater/score_hud.h, trick_watch.h) on the client tick only while a running plugin has events.tricks; a new level starts a new line. plugins::start takes the image base for it. - reskate-test has a tricks module (skipped until a trick lands) and ptest trick, which waits 30 s for one and prints what its events said; reskate-hostile has trick-loop. Not yet checked against real tricks in game.
