how to prevent 8 direction controler from moving when 3 or more direction keys are pressed?

Hi,

For the 8-direction controller, when the player presses the → & ← or the ↑ & ↓ simultaneously, the controller stops moving.

Like this, I'd like to implement a system where if the player presses the → ↓ & the ↑ buttons simultaneously, or any combination like this, I want the controller to stop moving in any direction.

Basically, if the player presses 3 or more movement direction keys, I want the 8-direction controller to stop moving. Is that possible?

I tried implementing this with the help of a variable. For example, If the player presses 3 or more direction keys, a variable will return "o". When this happens, I plan to disable the 8-direction controller.

The issue is that it seems to recognize when I press ←, ↓, → keys at the same time. However, if I press the →, ↓, ↑ keys, it doesn't seem to return a value.

Following is a screenshot of the event system I implemented. hope some one can guide me on this. Thanks for your time.

You can try something like this:

Global variable keysPressed=0

On every tick: Set keysPressed to 0

Key W is down: Player move Up, Add 1 to keysPressed

Key S is down: Player move Down, Add 1 to keysPressed

Key A is down: Player move Left, Add 1 to keysPressed

Key D is down: Player move Right, Add 1 to keysPressed


keysPressed>=3 : Player stop

Thanks for the tip,

just tried it, it doesn't seem to work :(

Faced the same problem as before, it seemed to recognize some inputs but not all.

I even tried mapping it to other keys. No matter what, the same thing happens.

Have linked the test Project below for your reference.

did a little more digging on this topic. looks like this issue was discussed.

according to it, it's mentioned that this is a hardware issue!

Yeah, it's called ghosting, you can test your keyboard here:
