Move orthographic camera with isometric view (Translate & Position not working)

[sarensabertooth]

Hello dear community,

I am completely lost here and any help would be greatly appreciated (I'll buy you a coffee via PayPal).
I am trying to have a cube on a grid system where position 0,0,0 is the far top or left square (it seems to be center by default).
I have pretty much achieved what I wanted to this point, but now I am desperately trying to move the camera to the left or right on the screen, so that the grid moves accordingly (horizontally).
However, all I have managed to do is set position or translate,
but both only visually rotate the view around the center point, which destroys the isometric view point.
It is possible to move the plane/grid around using the orbital controls and right click or arrow keys, but I want to do this using events or timers too.

I have tried a lot of things and online resources, but it seems to be that one case that isn't covered anywhere.
Basically this will become a 3D game but with isometric camera view (2.5D). I don't even know if the orthographic camera is really needed, I guess a perspective camera could be moved to where it achieves the same angle.

Check it out on codesandbox.io

Also side question: is there any way to logically attach the cube to the grid plane?

You can lock the camera to a certain angle, min/max theta, phi, azimuth, can't remember what it was, look into the docs you'll find it. If you do that you won't be able to rotate, just pan. Or, use map controls, which has it pre configured.

I ended up simply changing

camera.current.position.set(0, 0, 0)
camera.current.rotation.order = 'YXZ'
camera.current.rotation.y = -Math.PI / 4
camera.current.rotation.x = Math.atan(-1 / Math.sqrt(2))

to

camera.current.rotation.order = 'YXZ'
camera.current.rotation.y = -Math.PI / 4
camera.current.rotation.x = Math.atan(-1 / Math.sqrt(2))
camera.current.translateZ(100)

and I removed my orbit control object, as I don't need that anyways.
It seems like an ugly fix, but it works for me. Now I can set position.x and position.z at the same time to move my grid map horizontally.
