collisions with isometric games

[mussashimits]

Hi,
I'm trying to figure out how to make collisions is my isometric game. I am inserting backdrops and clicking on "Obstacle" as its type. Then I'm rotating the solid square so it's diagonal, like my isometric level. However, my character that's supposed to Stop Movement when it collides with background, goes right through it. Any ideas on how to fix this? Thanks very much!

That's not the way it works. Even when you set the Backdrop to Obstacle, you still have to tell your sprite how he has to act when he collides with the Obstacle. You need an Event for that

Sprite collides with Obstacle --> Stop

Or do you have this event and it doesn't work? Then it may be because of your Movement type. Custom Movement Engines like setting the sprite pixelwise across the level doesn't care about stop. Where there's no movement there is nothing to stop

Well I forgot to mention that I did set that event:
"When object collides with background, stop movement of object" Sometimes it collides, but most of the time it goes right through the backdrops.

You still don't mention what movement you use too. And there may also be some code overriding this stop command

So in this case your question is to vague to answer usefully, sorry.

What about a simple example that you upload in the file archive to show the trouble ?

Take a look at my Isometric Gaming Tutorial. Follow the link below and you'll find the tutorial on the Click Software page of the KnightTrek Productions website. It covers collision and other isometric matters.

Something I forgot to mention- the way I'd making th movement is this:
Repeat while player presses right arrow- set object A's position at 4,-2 from object A.

Is this method of player control my problem with the collisions? If it is, how else would I make my isometric movemt?
THanks
