Hi @Yokiyami,
Welcome to the forum! 😉

(disclaimer: `ArrayList` is also a class eheh 😋)
I think the issue is caused by your use of the `mousePressed` variable.
Since the `draw()` function is being executed roughly 60 times per second, if you check something related to the `mousePressed` variable then from one frame to another it can be `True` then flipping your card twice if you keep pressing the mouse.
See this example:
```processing
void draw() {
if (mousePressed) {
println("mousePressed true at frame " + frameCount);
}
}
void mousePressed() {
println("mousePressed()");
// Flip your card here...
}
```
If I click only once on the canvas, I get this:
```plaintext
mousePressed()
mousePressed true at frame 35
mousePressed true at frame 36
mousePressed true at frame 37
mousePressed true at frame 38
```
So you see that it’s triggering the condition multiple times which is not what you want.
Instead you should be using the `mousePressed()` function (as shown above) which is triggered only once per click.

I have tried that in multiple ways, i just cant seem to get it work… FML

I can’t help more without any code 😉
What you should do is make a simple proof of example of your game without any external files (images we can’t test)

I dont even have a clue how to make that simple proof of example… Yeah i could start from scratch, or start replacing all the image related code and use something else instead of that, but i have a deadline this sunday and i have a report to write also, so i really hope someone can help me in the right direction…
Dont know if this is possible, but i have uploaded it via wetransfer, i dont want my code to be publicly available so everyone can use it. Can i DM it or something?

Try to put this code into the `mousePressed()` function.
