Check if coordinate is within sprite

[krabban]

Hi!

I want to check if a coordinate is occupied before I spawn a new sprite.
Are there any easy ways of checking if a sprite occupies a given coordinate?

Something like:

if( !isOccupied( x, y ) ) {

    //Do something

}

 

Any help or pointers would be greatly appreciated.

How many sprites do you have? You probably want to iterate over them in a for loop and see if they are in that space.

Sorry, I didn't phrase my question as well as I should have.
 

if(x and y equals sprite.x and sprite.y) {
    // Do something
}

If I'm understanding this right, this snippet only returns true if my x and y equals the sprites x and y.
This might return false even if my x and y are within the sprites collision body.

I need something like:

if( !(x and y are within sprite.collisionBody) ){
    // Do something
}

But I'm unsure what to compare against.

If you want to do this you need to check every sprite in your game and see if it overlaps that point. If you've enabled physics for your sprite then it has a property called "body" that has properties x, y, width, and height. Those form a rectangle that you can use to check for intersection with your point.

if (!(sprite.getBounds().contains(x, y))) {
    // Do something
}

... is probably what you're looking for.

getBounds() returns a rectangle on which you can call contains() with x and y.
