How to map Device Acceleration to XZ Axis Movement

(1/1)

rndmoo:
Hi,

Is there a clever way of mapping Device.Acceleration to XZ movement like to Character Controller with Axis Input but for Device Acceleration? Or convert Device Acceleration to Axis Input?

You'd have to check the accelerometer's position at every frame using a low pass filter and compare it to a reference vector. You then can check the direction and/or the angle from the device's orientation to the reference vector. You can use this information to move a character around, etc. For example, you can use the angle difference to determine the character's speed.

I use the accelerometer to move a character around in my current project. It's really easy once you understand how it works. Unfortunately, I only use Playmaker for AI in my game. All else uses custom scripts that are sometimes linked to Playmaker FSMs.
