Tilting (Android)

[brooky1010]

Hello, I have some problems with moving my player sprite with tilting.
The app I made if for phones that stand up (not landscape mode).
I want when they tilt to the left my player rotates to the left and when you tilt to the right my player rotates to the right. I tried several things but none of them work.
And also when I tilt forwards it adds 0.3 motion to my player. Thanks!

For portrait mode, the function you want is device_get_tilt_x. You'd use it much like how you use an analog stick on a game pad: 0 is neutral, -1 is all the way left, 1 is all the way right.

Unlike analog sticks, there is no option to set a dead zone, so you'll want to add code to compensate, because next to nobody will ever hold their phone exactly upright.

Example:

tilt = device_get_tilt_x;

if (tilt > 0.05) {hspeed += tilt * 4;}
if (tilt < -0.05) {hspeed -= tilt * 4;}

This makes it so that your object has an acceleration of 0-4 in the direction of the tilt, but ignores tilts less than 4.5 degrees (0.05 * 90 degrees) from neutral (straight up and down).
