Use UI buttons for movement

Questions & Answers

So I have a basic 2d movement script that works with Input.GetAxis just fine. Now I’m trying to change the input to an on-screen d-pad for mobile. The problem is it is only running the movement once and then won’t run the function again.

     public void goRight(BaseEventData eventData) {
        			inputX = 1;
        			buttonheld = true;
        			Debug.Log ("You should be going right");
        		}
        		
        		public void release(BaseEventData eventData){
        			buttonheld = false;
        			inputX = 0;
        			inputY = 0;
        		}

void Update ( )
		{
			
			if (buttonheld) {
				
								if (inputX != 0 || inputY != 0) {
										
										Move (inputX, inputY);
								}
						
						}

This is the gist of what I’m doing. Any insights would be great.

OK, not got access to Unity so this is just from my head. Place your four buttons/Images on screen and create a script that has eight public functions in it.

public void UpButtonOn()
{
    upButton = true;
}

public void UpButtonOff()
{
    upButton = false;
}

// repeat for left, right and down

Then in update just check those bool values and if true do the movement for that direction and handle events like left and right being pressed at the same time cancelling each other out. Call it DpadScript.cs

Drag that script onto the canvas directly.

On each button/image add an EventTrigger Component and add events to trigger on PointerEnter and PointerExit so for the up button add PointerEnter Event and drag the canvas (with the DpadScript on it) onto the slot that appears then from the dropdown select DpadScript → UpButtonOn.

Add a PointerExit event and repeat but put it to DpadScript → UpButtonOff.

Repeat that for each button adding a PointerEnter and PointerExit to the correct function to set the bool.

Should work but can’t test as I don’t have access to Unity at the moment.
