Hi, I’m searching since some days ago a way to modify the control of the Car Challenge demo.

By default, when press to left or right the cars rotate, and I want to change that behavior to a like action RPG control like Zelda: A link to the past or Soleil.

I just want when I press to left, the cars move to left, when I press to right, the cars move to right, instead of the default rotation behavior. And obviously, when I press down, the cars move to the bottom of the area or the window.

I doesn’t mind if the cars don’t rotate automatically after doing the changes.

Hi,

there are numerous ways for creating such movement, the CarChallange demos using physics and the keys are modifying the physical properties force and torque of the car collider.

force: Qt.point(twoAxisController.yAxis*8000, 0)
torque: twoAxisController.xAxis*2000

You could remove the torque and instead do something like this on the force:

force: Qt.point(twoAxisController.xAxis*6000, twoAxisController.yAxis*6000)

Now the car won’t rotate but only move in x and y direction.

You could also e.g. use a MovementAnimation to move the character constantly if a key was pressed.

Cheers,
Alex

Thank you very much. Putting a negative value to y Axis I get the thing I want.
