Blocks & Holes

Create a new object block with the sprite. 

Make it solid and set the parent to "wall".

• Collision with person
• • Check Empty:  (4*other.hspeed, 4*other.vspeed); objects = "All", relative.
  • add Start and End blocks, between them add:
  • • Play Sound (push)
    • Jump to Position: (4*other.hspeed,4*other.vspeed), relative

Go into your person object and add a Collision with block event - add the Comment "do nothing" (this just helps make it work, prevents some other action from automatically happening).

Go into your testing room, add a few block objects (not near any walls) 

Test it out - does the person push them in all directions?

Create a new object hole with any sprite from the "holes" folder.

Make it solid and set parent to "wall" (so the person can't go through it).

• Collision with block
• • Play Sound ("hole")
  • Destroy instance (self = hole)
  • Destroy instance (other = block )

Go into your block object. Copy the Jump to Position action and paste it below.

Now add Else and then Start and End blocks around it.

Inside the bottom section, add 

• Check Object: object "hole", (4*other.hspeed, 4*other.vspeed), relative

Now place a few holes in the testing room with walls - one really close to the person so we can quickly check that the person can't go through it. The other that we'll push a block into.

Test it out:

• your person should not be able to go through them, and
• if the block collides, the hole should disappear.

Have your game playing and get it checked ...
