check if any sprite exists at x,y coordinates

[owen]

Hi, very simple newbie question again sorry.   I need to check if a sprite (or, any sprite at all) exists at x/y coordinates within the game.  The reason I want to check is when I spawn a sprite I want it to be within a free space instead of on top of an existing sprite.  Any ideas?

 

So something like this:

If (game.spriteExistsAt(150,380)==false) {   // there's nothing there, spawn a sprite}

Thanks

Owen

sprite or body?

there is a checkhit function that checks at given x,y coordinates for a physics body and returns an array of bodies..

Hi @valueerror what is the true name of the "checkhit" which you are talking about ?

Just a last question @samme, is there an equivalent of getObjectsAtLocation based on sprite's physics body or i need to check it manually by iterating over the array returned by this function ?

@Kiwi404 getObjectsAtLocation checks physics bodies (the docs don't make that clear).

It's actually using Arcade.Body#hitTest so you could us that too if you prefer.

Indeed I saw it while experimenting, it use physics bodies coord instead of sprite's coord.

Thanks !
