How do i check if a space is empty without arrays?

Whatsup peeps long time no talk!

I was wondering how I can check if a space is free without using arrays.
I want to make a gun shoot if space in front of it is free. But the space can be blocked at any time

I want to make sure that this is checking every tick unless there is another wayTheNewGuy2013-07-16 04:57:05

- Sprite: Is overlapping at offset
- distance(x1,y1,x2,y2)
- use second sprite to test for collisions.

All depends on your game and what you want to do.

why did you ask about "without using arrays" ?

@shinkan will this method be able to check if the space is free as a constant. For instance when I place a tile in front of it,it will stop shooting?

And I was saying no arrays because the last time I tried to get information someone told me to use arrays

Yes.

@shinkan I have one other question if I use the overlap at offset wont that just check once?
Or will I have to call for every tick bro. I want the player to be able to stop incoming rounds by placing a tile infront of the gun but when he removes the tile the gun shoots again.

Depends on You. If You use a trigger it will check once, if "every tick" will check every tick.
