* level7_crack1# Entity Script
* 
* Author: GD
* Date:   15 June 2002
*
* Desc:    A green door Crack/Door script, this appears as a crack in a 
*          wall, when exposed to a bomb it crumbles.
*
* Usage:  Place in the Landscape Designer.
*
*         Use SetString() to place the identifier of the door you want this one
*         to lead to into the first string of this entity, i.e:
* 
*		      SetString("thisdoor", 0, "targetdoor");
*
*		  Then it should automatically take you to the target door when you go
*         Through this one.
* 
*         CallFunction("door1", false, "Open", "NULL");   To open the Crack
*
