Align custom cursor's click position with world?

Sosasees

I am making a game that's controlled with custom cursor logic. But the output of this custom cursor is offset because I set the camera to align the playing field to the bottom (instead of the top):

I need a way to correct the position of the output so that the taps would land exactly where the player would think they'd land.

If you're asking for a minimum reproduction project: Besides deleting the (in this version decorative) GUILayer CanvasLayer, I can't strip this project any further before it no longer shows the point of the question.

Very interesting question, The root cause is that the coordinates of the upper left corner of the camera are different You can perform coordinate transformation manually, like this

If free conversion of resolution is not allowed in the game, you can directly save center_y and size_half_y

Thanks very much. I forgot to make a comment (the day before this comment) that I found a solution that fits my game. But yours works much better and has much less code. I could not have done that myself.

My solution - works when making the aspect ratio taller, but not wider. - loses precision the taller the aspect ratio becomes.

Your solution has none of these downsides.

Now I have to clean up the code by moving the position calibration logic into its own node, since in good programming, no code should be repeated. But this state is much better than having to write the logic from scratch without knowing where to begin.

I am very happy to solve your problem, My code just provides ideas, Please feel free to change ;)

After my attempt to clean up the code, it broke. ([Project, .ZIP](https://godotforums.org/uploads/editor/ml/dt3vazxym2ug.zip ))

The great news is, that, while it would be nice to have cleaner code, what's actually important is that the game works as intended. Because your code works as I need, I can immediately continue with the next part of my game.

I rewrote just the one script in the PositionCalibrator node, and now the entire thing works as intended. This is the power of the modularity of nodes, if used correctly by giving each node just 1 responsibility. It's a little bit hard to understand, but this is the "single-responsibility principle".

If you're wondering why the cursor visuals are now offset: I didn't care about keeping the cursor visuals aligned because these are just for debug purposes and will be completely removed very soon when the game is a little bit closer to being finished.
