at the end of animation do fade. So then the last frame will fade and the object will be automaticly destroyed.

this is quite a good tutorial: scirra.com/tutorials/548/simple-ladder-for-platformer-game

made a capx with the tint webgl like vee41 suggested

i can perfectly move. I pressed P1. then left or right and he did what he needed to do i think. Keep moving left or right.

so we meet yet again Kionysan xD.

sometimes there is no short way like a motion tween. Just make a small animation and let it loop. Also use ping pong you only need to make it go from black to red and with pingpong it auto reverses the loop.

small example. (go to edit animations and you will see the settings)

Edit: Forgot about Webgl xD thanks vee41

what you can do is a wait after a certain condition is met

on loaded layout1 : System wait 5 seconds -> go to layout2

on loaded layout2 : System wait 5 seconds -> go to layout1

small example from my tower defense for draging and dropping towers.

i made a tower defense a while ago called tiny defense.

Here is the small snipet to make it snap when holding.

that part is fixed now. I make the reset do a full reset like it was intended. Since in the newer levels you can fail by throwing things into the abyss. So you'll need to restart.

There is a lot changing now and i need to put a new version online.

EDIT: new version online with the same link.

for X:round((Player.X - 16) / 32) * 32 + 16

for Y:round((Player.Y - 16) / 32) * 32 + 16

This is to check on your grid (32 by 32). So if your character is on a tile and hits 3pixels in front o him you check that x with your X where you hit or where you put something. So it snaps to the grid

small example i made:

is it straight that he needs to move?

there is smething like disable platform or just disable movement. Then do simulate movement right or left or what you want for a certain time or untill he is over a trigger (invisible little object). Then enable platform again.
