# How do I define dragging area?

Get help using Construct 2

### » Sun Mar 18, 2018 1:00 am

Hello.
I have a joystick in my game that is working with no problems.
Now, what I want to do is settling the dragging area, right now, it doesn't matter where I drag the stick, it will just follow wherever I touch.

So I want to define the stick a specific area that the stick couldn't get out of.

This is the stick

And I want it to not be able to get out of this area

But, when I'm out of this area with my finger (or mouse), I want the joystick to keep dragging the stick, so I could get the angle from the joystick virable, but the stick won't bother the player while he's dragging the stick (whenever the player is dropping the stick, he gets back to the original spot.)

Thanks!

Here you go:
https://www.dropbox.com/s/h67nu1sqfome3 ... .capx?dl=0

You can replace event #2 with this:
Small->Set position to Big
Small->Move at angle (angle=a, distance=d)

Hey, I was trying to do the same like that

But it doesn't work, maybe becuase of something that is written here?

Thanks for your time

Edit: I have 2 joysticks in the game if that matters

You can't use drag&drop on the same sprite.
Create another (invisible) sprite with Drag&Drop behavior, say "dragSprite".
Remove Drag&Drop behavior from the "sangStick".

Change events to this:

dragSprite is dragging -> set AreaAngle to angle(sangPad.X, sangPad.Y, dragSprite.X, dragSprite.Y)

The rest is the same.
When not dragging, return both sangStick and dragSprite to sangPad posision.

Shouldn't that work?
I don't really understand why I need to use a second sprite to define the drag, the drag also define me the conAngle that defines the player movement, there's no way to use the same drag and drop that I already have?

something like that

If you move the finger outside the sangPad, dragging will be interrupted, because sangStick can't move further.
That's why you need a separate invisible sprite that can be dragged freely.
It's a popular trick, you can see an example here:
