Is there a way that I can tell if dialog elements are overlapping each
other? I've tried several times to attempt to solve this problem and I
have come up with no solution. Confused

I've tried something like:

If the elements can use a STYLE, ya can test it using a
background color to show where it's actually located... Wink

Thanks for the idea, but I should make myself clear: I will need to be
checking through code, not the human eye.

But thanks anyway! Very Happy

Ok... why do ya need to check element overlap with code? Confused

It'd help if we know what you're tryin' to accomplish... Wink

Sorry...

It's for a type of "game" in which you have to avoid obstacles. If one bitmap
overlaps the other then basically you've hit an obstacle.

I'm pretty sure that it would work with some type of code using @dlgpos(),
but I'm not sure about the math that's needed.

I hope this helps you understand better. Wink

OK - I'd keep the element names and positions in a list something
like this:

Element1|30|100

You can then find it with @match(), PARSE to check it's position,
and update it as needed. If the elements are different sizes, ya
can add the width and height also. Wink

Another thing ya might do is cut your layout into an invisible
grid, and when a piece is in that grid space, mark it as occupied.

It's been a while (so I don't really remember), but I prolly used
this method on the checkers game... Wink

They're all good ideas, but in my case I don't think they will help. Sad

The reason for that is that I generate a random number of bitmaps
and you need to move left or right to avoid the oncoming objects.

I'm thinking I'm closer with @dlgpos() to get the object position and the
other object's position and do some math calculations and come up with
an answer to whether they're overlapping each other or not.

Thanks again for all of your ideas and help, they are greatly apprecieated! Very Happy

Well, it's your baby.... Wink

The thing is - if ya gotta check all positions of every piece,
I think it'd be faster/easier to run thru a list in a loop. Ya
would put the location data in the list when the elements
were created.

I'd like to see it when ya get done. Smile

Question - are all the pieces we're dodging the same size?

Mac · Posted: Tue Feb 18, 2003 10:29 pm Post subject:

Never mind... here's a basic collision detection routine if that's all
ya wanted. It's not tested, but ya should get the idea... Wink

FreezingFire, the loop Mac is telling about is in a way the same as all the MouseOver codes that are posted over here... Maybe you should take a look at one of those?

Mac · Posted: Wed Feb 19, 2003 2:09 pm Post subject:

Slight difference - ya gotta allow for both the width/height of the
player and width/height of the object... Wink

Well, if FreezingFire uses your code, and the loop of one of the Mouseover codes, it might work...
