Avalon: Routine at 53323

53323: Creature collision check with room boundary and Maroc

Used by the routines at 52695, 52948, 53003, 53054 and 53080.
Check if a creature has collided with a room boundary or Maroc: Uses the generic room boundary check routine at 57401 which checks for collision with the room walls, and if so, adjusts the creature's position Checks if a creature is at Maroc's position on screen/in room If so, reduce Maroc's energy based on the damage that creature type deals (last byte of creature data set at 27828) If the creature is a WRAITH, check if the WRAITHBANE spell is active & if so destroy the wraith
53323	LD A,(60572)	FREEZE spell timer counter (> 0 means the FREEZE spell is in effect)
53326	CP 0
53328	JR NZ,53392	Maroc doesn't lose energy if he touches stationary creatures when the FREEZE spell is in effect
Check creature is within room wall boundary, adjusting if needed:
53330	LD A,(60234)	Creature's vertical pixel position in room
53333	ADD A,8	Adjust the vertical point to check for collisions 8 pixels down, towards the middle of the creature, rather than the top
53335	LD E,A	Store in E register, which is what the room boundary is checked against
53336	CALL 57401	Run room boundary checks for creature, adjusting position accordingly if needed
Check collision detection with Maroc
53339	LD C,0	Collision event type 0 = collision with Maroc
53341	CALL 57293	Run collision check
53344	CP 0	The A register is returned with 1 = collision, or 0 = no collision
53346	JP Z,53885	If no collision, can jump out of the entire routine here
The next routine follows if a creature has collided with Maroc
