PRACTICE > TELEPORT now shows the waypoint the player placed on the game's pause map, with a "Go to map waypoint" button. The console gets `trainer waypoint [info]` and `trainer ground <x> <z>`. Reading the waypoint (trainer_waypoint.cpp) - It is a point of interest in the map's registry, the one ReSkate's party markers register into (addr::native_party::map_manager), with kind DingoMapPOIType_Waypoint (3) and its world matrix at @0. - The registry is walked only while the TELEPORT card is drawn (the page notes it, like the class list) or the command runs, every 250 ms at most. A player who never opens the card pays nothing. - A registry the map has filled without a waypoint means it was removed; an empty or unreadable one keeps the last waypoint seen. A new level forgets it. Landing on the surface (trainer_landing.h) - The waypoint's height is not the ground: teleporting to it dropped the skater through the map. local_ground_height() casts the park editor's downward ray (editor::cast_surface) through the client physics world and takes the topmost hit. - The first ray starts at 1500 or 500 above the hint. A custom map can sit higher than that (a waypoint at Y 12 over ground at Y 1939 was seen in game), so a miss is cast again from 20000. - If collision there is still streaming in, the teleport goes to the hint's height and a 12 s watch puts the skater on the surface when it arrives (at most 6 corrections; the teleport is re-sent up to 3 times if it never arrives). - Teleports still go through go_to(), so they follow the host's noclip / teleport permission in a session. The decisions (ray spans, the watch, remember/forget) have no game in them and are tested by trainer_landing (DINGOSDK_BUILD_TRAINER_TESTS). README and CHANGELOG updated.
