LADDERUP2

Description

Extended ladder-climb (“up” direction) that follows a three-waypoint path. Nine coordinates are popped and stored as fixed-point world coordinates (shifted left by 12): the first point into move_pos_x/y/z (entity+436/+440/+444), the second into move_target_x/y/z (entity+448/+452/+456), and the third into a further coordinate triple (entity+424/+428/+432). The inline 16-bit argument is the destination walkmesh triangle ID (entity+508). The handler sets motion_state (entity+572) to 4 (three-point ladder mode) and seeds the direction field move_angle_current (entity+538) with 1 (up). Unlike LADDERUP it does not start an animation itself. It pauses the script until the motion completes.

Identical to LADDERDOWN2 except for the direction seed (1 for up, 0 for down).

PC handler: SCRIPT_LADDERUP2.
