Mobile touch buttons not enough

I wonder why he did not help anyone’s touch interface on a mobile game developer, what a help item is a video about this topic,
How can I customize the touch trackpad
How can we grade these key position “as the vehicle to move more slowly”
available from mobile keys are difficult to very dysfunctional and motion control
please help
with love

As you can detect touch postions, you can code your own virtual controls UI, maybe you should think this direction

Thank you for your interest,
but I do not know how to do the coding, I have to do something on my own,
available from the keys remain very dysfunctional, it is hard to control the car, I can not figure it

Usually if you want more than analog sticks and a few buttons for your touch interface, or you want more flexibility in your touch interface’s behavior, it may be best to use UMG widgets INSTEAD of a TouchInterface. It’s a different approach and you’ll need to learn how UMG works, but once you get the hang of it, it’s very powerful.
