i wanna make a function that returns (or sets a value to what a sprite is touching) because I can’t find a pre-made variable in the engine that does it, like sprite.x returning the x coordinates.

but if there isn’t, here’s the basic system ive come up with but i can’t figure out the problem.

var item1 = createSprite();  
var item2 = createSprite();

var entities = ;  
appendItem(entities, item1);  
appendItem(entities, item2);

function touchingWhat() {  
for(i=0;i\<entities.length;i++) {  
if(player.isTouching(entities[i]) == true) {  
return entities[i];  
} else {  
return “nothing”;  
}  
}

you can only use that if your using a group… your using an array

```auto
var entities = createGroup();

```

that function is an extention of the Array class data structure otherwise there will be a failure and you will be forced to iterate through the items on your array to compare .isTouching() since Array.prototype.isTouching is not an inherent function
