Hello all. Trying to find the easiest way to capture user input on an encoder wheel. In theory, I would want to track the clockwise / counterclockwise mouse movement within the area representing the encoder. So instead of just moving a slider left to right or up and down, the user can actually rotat…

Another way of approaching this problem is to create a Ticker class and feed the raw IncrementalEncoder values into it. class Ticker { float pos; float lastTick; float step; Ticker(float start, float step) { this.pos = start; this.lastTick = start; this.step = step; } …

Please look at the GUI libraries Such as G4P or controlP5 They should have this

I was hoping for a way without a Library - but I guess this does answer my question on the “easiest” way… Edit: Also, neither of these libraries have the kind of “knob” or “encoder” I am trying to make.

I think this looks more promising! Thank you!

Hello, Thanks for asking this! Had some fun with it… Sharing my initial steps… I did not look at other examples. Create a PGraphic image. I used random circles but this could be your encoded wheel or anything. Move the mouse over the canvas to detect colors. Do something with the detected color…

[image] rkdnson: the user can actually rotate their mouse around a center point. Do you want an absolute encoder, which gives an angular location value in some range (0-360) – or do you want an incremental encoder which produces an offset value (e.g. 0.1 or -0.05) each frame depending on how …

Wow! Thanks all, Im glad I checked back up on this. I will look at the code above - but to answer your question… I think an Incremental Encoder would be preferred!

[image] rkdnson: Incremental Encoder This can be tricky for a few reasons – PVector.angleBetween is unsigned PVector.angleBetween doesn’t return the minimum arc display components like arc() have similar behaviors – they are rooted and directed Here is one example of a solution. /** * In…

revisiting this. This solution is my current implementation, however I am finding that it is a little difficult to stop on a specific number. I tried using modulus on the sum to mimic a “tick”, and only outputting at 0. However, this doesn’t really work well. Is there another way you could go about…

When you say “a specific number” what kind of range and sensitivity are you looking for? Are you trying to dial between 0 and 10, or -100 and +100 – are these numbers integers? Do you want the knob to turn a quarter turn for a “tick”, or a tenth of a turn?
