Questions

[https://playground.babylonjs.com/#016FYM#34][playground link]
This is the second time I post for the same problem. I’m sorry but I need a quick solution to the problem.
I try to create an earthquake game with Babylon js.

I want to change createTank(line 24) function’s some properties on keydown and keyup.

If I am able to change the height and speed in keydown and keyup then it’s enough for my work. But I don’t understand how to change it in the right way. And how to show the changes in every keydown and keyup event.

Any help would be ok.
Thank you, everyone.
