Creating Ladders

Following is a list of guidelines for creating ladders for use in the CRYENGINE.

Ladder Measurements

• The pivot has to be 25cm below the upper edge of the first rung.
• The distance from upper edge of the rung to the edge of the next rung: 25 cm.
• The distance from upper edge of the last (grabbed) rung to upper edge of the whole ladder object (proxies are also taken into account): 75 cm.
• The length of each rung: >50cm.
• The number of rungs: 7 + multiples of 2 (the initial "start climbing ladder" needs 7 rungs. A climbing cycle is 2 rungs long); i.e. 10 cycles on a ladder needs 27 rungs (7+ 10*2).

Collision/Proxys

• The ladder needs to have a nodraw collision proxy for player/bullet collision.
• The ladder needs to have a box-proxy that roughly defines the area the player can push a button to use the ladder (Ladderbox).
• This Ladderbox needs to have a separate matID with the mat_ladder surface-type.
• The Physicalization of the ladderbox has to be no_collide.

Positioning Before Export

• The player will be facing the negative y-axis while climbing up/down the ladder. So, the pivot orientation of the ladder needs to look like the pictures below.
• The position of the pivot point is the reference point for the animation so it is highly important that the pivot is centered in the x-axis of the rungs and positioned as described above in the ladder measurements above.

This is the correct position for the rungs and the pivot (Top View):

These are the correct distances for the rungs (Front/Side View):
