I put the game maker on and then wnet thru the controls...

I tried put ground down, then found a thing called "Terrain" ok....


Then I teried put monsterts there, and found a thing called "Models" then when I hit the play button heres what happenned....

The ground apperedf and the monsters but they was in the air and they dont stay on the ground, then when I move with the arrows I can go RIGHT THROUGH the ground!
