[flt1]
X-coordinate of one corner of area

X-coordinate of other corner of area

This conditional opcode returns true if the player is in the rectangular area regardless of the player's z-coordinate. It allows you to mark the area's highest ground z with a cylindrical marker, colored blue in GTA III and pink in Vice City. The opcode must be placed in a loop with wait 0 in order for the marker to remain drawn in the world. In GTA III only, if debug mode is switched on, a debug square will also be drawn along with the marker denoting the boundaries of the area.
