Arguments

  • const UShort 0: Zero. Has an unusual effect on co-ordinates if non-zero.
  • const Short X: X-coordinate of the end of the ladder.
  • const Short Y: Y-coordinate of the end of the ladder.
  • const Short Z: Z-coordinate of the end of the ladder.
  • const UShort I: ID of the walkmesh triangle found at the end of the ladder.
  • const UByte K: The keys used to move the character on the ladder.
  • const UByte A: Animation ID for the field object's movement animation.
  • const UByte D: Direction the character faces when climbing the ladder.
  • const UByte S: Speed of the animation whilst climbing the ladder.

Description

Causes the character to climb a ladder; that is, switching from standard walkmesh movement, to climbing along a line connecting two points on the walkmesh.

The coordinates specify the end-point of the ladder; the current position of the character is used as the start point. The ID of the walkmesh triangle must be specified; this is the triangle the character will step onto after reaching the end point of the ladder. The K value specifies the keys used to move the character across the ladder; keys outside the range found in the table will cause unpredictable behaviour. The animation ID specifies an offset into the field object's animation list; this animation is played at the speed specified by S whilst the character climbs. Finally, the D argument is a direction value in the game's standard direction format, which orients the character on the ladder.

This opcode is used as part of the character's entity, rather than in a seperate entity, as with a LINE. A LINE is used to set the start point of the ladder on the walkmesh. When this LINE is crossed by the player, a script in the LINE then uses a PREQ (or one of its variants), calling the script in the party leader that defines the LADER, causing the character to begin its climbing position.

To set up a two-way ladder, two LINEs are used at either end, with different values for the LADER arguments, such as differing end points.
