In Mouse Object manual is written:
If you only use left clicks, consider instead using the Touch object with Use Mouse Input set to Yes. This will allow your game to work on touchscreen devices without any further changes.
In Touch object manual is written:
The Touch object also provides input from the accelerometer (motion) and inclinometer (tilt/compass direction) if the device supports them.
How can I use touch object, or touch input without accelerometer or another futures.
One example when I want to play Game whit touch in my HTC desire
