GameMaker Change the image_xscale of a specific object?

[Bokkie2988]

Hello,

How would I adress a specific object and change its image_xscale?
I tried using this :

var weapon = instance_create_layer(x+8,y-3,"Player",oEnemyPistol);

if (image_xscale = -1) weapon.image_xscale = -1;

But the game gives a error code saying

local variable weapon(100002, -2147483648) not set before reading it.

Can anyone help?

Try making weapon an instance variable instead of a local variable. If that doesn’t work then I have no idea.

If that code is actually together like that (in other words one line after the other in the same event) it should work if the instance_create_layer works. So one possibility is that it is not working - perhaps because the layer doesn't exist. If those two pieces of code are not together, or if you are using the

if (image_xscale = -1) weapon.image_xscale = -1;

line elsewhere then because you have made weapon a local variable it will cease to exist after that event/script that it is being called in.

I'd run this with the debugger turned on and see what the variable actually holds. See:Debugging with GMS2.

I would also fix the operator you are using from an assignment “=“ operator to the comparison “==“ in your if statement.

What you may want to try is this:

//Using the "with" block directly addresses the object being created.
with(instance_create_layer(x + 8, y - 3, "Player", oEnemyPistol){image_xscale = -1;})

Thanks to everyone for helping. The problem was that the 2 lines of code were not directly after eachother, there was some other code between it. Apperently that's not allowed in GMS2. Thanks!

It is, as long as the local referenced variable ‘weapon’ still exists and is an instance id.

Out of curiosity, what was the code in between? It doesn't sound like your solution was an actual solution.
