How do I make a top view object slide on wall/solid ?

I didn't use the 8 Direction behavior and I made my own set of events. I only work with 8 directions (angles of 45°) and managed to get the sprite to slide on walls by adding collision detectors (Left and Right) ahead it. The issues is the following:

At event 4 the collision is checked only with one solidWall, so when reaching a corner made from 2 solidWalls the event doesn't work how I would like.

How can i resolve this problem ?

Also is there any difference if I use Sprites or TiledBackgrounds for the solidWalls since both can cover a rectangle collision and support angle change ?

Do you mean you get to a Y shaped wall? If so why not put an invisble trigger at this point.

Here is a demo of my project:

[Arrows] - Move

[X] - Attack

Anyone ?

How about trying the Pushoutsolids behavior which is here.

It might do what you want.

For that you could add a pick all solidWall condition between the overlap conditions.

While Rex's plugins are very good, I prefer to not use 3rd party plugin unless is something that it can't be done in events (or is extremely complex to implement it in events) because updates sometimes break these plugins.

I've tried this before, but no luck ... I've attached a stripped down version of my .capx to see my events.

I mean putting the "pick all solidWall" in between you overlap conditions.

So instead of what you have now:

PlayerAheadLeft is overlapping solidWall
PlayerAheadRight is overlapping solidWall[/code:27k6r58q]

Do this for all 4 of your events:
[code:27k6r58q]PlayerAheadLeft is overlapping solidWall
Pick all solidWall
PlayerAheadRight is overlapping solidWall[/code:27k6r58q]

Thank you, it works exactly how I want just by editing the second group of conditions

Else
PlayerAheadLeft is overlapping solidWall
Pick all solidWall
PlayerAheadRight is NOT overlapping solidWall[/code:r0meqnr6]
So in short after the PlayerAheadLeft is overlapping solidWall, [b]reset the picked solidWall[/b] and then check again with PlayerAheadRight
