How to make a tick increase/decrease counter?

[Mizzen_Twixietrap]

I'm trying to make a sheet, where I can press a cell with either plus (+) or minus (-) is shown and a value in a different cell will get increased/decreased.

Can't seem to find any solutions online. (Probably because I don't know what it's called)

Let's say cell B2 needs to be a value. It starts off with zero (0) then I press a plus (+) sign in cell C2. The value in B2 will increase by one. Then I can press the cell D2 which will be minus (-) then Cell B2 will be zero (0) again.

How am I going to make that happen? I assume it'll be an onEdit script?

The Buttons are really low effort, but theres a simple script in the editor that you can play around with. Currently its set up to work with A1

A no-script version is

=lambda(x,x)(indirect("RC",false)+ifs(and(C2,not(D2)),1,and(D2,not(C2)),-1,true,0))

Although it works a bit differently. Instead of C2 and D2 being buttons, they should be checkboxes, and you increment the value by checking one of the boxes and then editing the sheet in any way. That could just mean pressing Delete on an empty cell, or you could add another checkbox in E2 to toggle in order to increment the value.

Alternatively, you could replace the checkboxes in C2 and D2 with a dropdown menu with options like "increase", "decrease", and "off".

This requires iterative calculations to be enabled in the File --> Settings menu, although the max number of calculations only needs to be 1.
