Keep Boss On Dungeon Floor

Hi All

My dungeon is made from 30 x 30 sprites including walls, dungeon floor, monsters etc.

I have a boss that I want to move each time the player moves. I figured on mouse click get the boss position

and move 30 pixels in a random direction, problem is the boss moves over walls etc.

How can I make him stay on the dungeon floor only.

You got to make a condition that walls can't be selected

The boss moves automatically in a random direction + or - 30 pixels both X & Y.

I wondered about using overlapping at offset but can't get it to work

if you are setting the position manually, you need to also check if it's over a wall, after moving the boss, have another check for if the boss overlaps a wall, if so, either move it back or move it somewhere else.
