Triggers

Shape: The shape of the trigger in 3D space (Sphere or Box). Below this option you may specify the size you want as either a radius (Sphere) or as Width, Depth, Height (Box).

Trigger Resets X Times: Specify how many times the trigger will work, where "X" is a number you input. A setting of -1 means the trigger will always work. A setting of zero means the trigger will never work (bad idea). For example: If you want to trigger a one time event, use 1.

Trigger Resets after X Seconds: Specify a delay before the trigger becomes "active" again (usable), where "X" is a number you input. Using zero here will make the trigger work as fast as possible.

Activated By:

Players Only: Only the player can set off the trigger.

All Objects: Any object passing through the trigger will set it off.

Linked Objects: Only object linked to the trigger will set it off if they pass through it.
