Argument

Destination walkmesh triangle ID (16-bit).

Stack

XCoord

YCoord

ZCoord

Climb animation ID

LADDERDOWN

Description

Moves this entity onto a ladder and climbs “down”. The top stack value is an animation ID that is started immediately (looping); the next three values are the destination X, Y, Z stored as fixed-point world coordinates (move_pos_x/y/z, entity+436/+440/+444, shifted left by 12). The inline 16-bit argument is the destination walkmesh triangle ID (entity+508). The handler sets motion_state (entity+572) to 3 (ladder mode) and seeds the climb direction field move_angle_current (entity+538) with 0 (down). It returns 1 (wait) while climbing and 2/3 on completion, pausing the script until the climb finishes.

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

PC handler: SCRIPT_LADDERDOWN.
