Spawn/Destroy block

I'm creating a platform game and I got stuck at something.

• Show 4-8 blocks in a row
• When the player walk over the blocks (individual), it disappear/fade out
• Wait 2 seconds
• The block should reappear/fade in in the same spot as it was before

It seems to be simple, but when I have more than one block in the screen it turns out a nightmare.

Please help

This is by no means a pretty solution, but it is a solution. Just note that the solid function was used and not the platform function.

It's not the best situation but I can use the idea to improve my project.

Ps. I found a bug on it. Sometimes it respawn on top of the player and fade out right away. I don't know if it will be a problem, just to let you know.

thanks,
