pushed blocks overlap

Hey guys, I'm trying to make a block pushing puzzle, but I'm having some trouble in the form of two related issues.

The first problem is that if the player walks into the block while holding z, the block can be pushed. but if the player is already touching the block and then tries to push it with z, it doesn't move. I'm assuming this is a collision issue.

The second issue is as long as the player is pushing the block, the block can be pushed through a different block so that they overlap. I want it so when a player pushes one block into another, he can't push it any further.

Strange, but for me, the first problem was not a problem - I pressed the player up against the block, then held down Z and I could push the block.

However,you may well have found a bug in your second problem - the game does not recognize the block's collision in your example!

Hmm.

Hmm..I can push the block on the left while up against it, but only if I'm going to the right. It doesn't seem to work with other directions.

There's a collision bug in r63 which is fixed in the next build. Hopefully that will sort it out.

ah, gotcha! Well here's hoping then =)
