Hi, i am trying to build a rotary knob control like this:

i am lost, i am using various layers and a texture progress but without success :frowning:
in the best case, the user will control its value by moving up/down or left/right…

anyone is successful doing this ? or any trick that can help on this task … please
i am sure i can do it, but how ?
i can do it ibn python, in C++ and js… but i dont know in GD

have a great day

Just made a simple knob.

It uses rotation degrees as knob value.
Shouldn’t be that hard to fit it to your needs.

There are probably better ways to make a knob, but this works fine for me.

You could also use knobs from KnobMan with AnimatedSprite.
I can upload an example if you want.

Edit: Knob with AnimatedSprite

Hi Adam_S, Nice ! the simple knob is awesome, this is the solution i was looking for.
