Thanks

I think that touchscreen actions just act like mouse click and drags, so act like it's just a mouse.

As for tilting, you can use the function getAccelerometer(); to do this.
To use the function, you declare it like so:

Code: Select all

Vector myvector = getAccelerometer();


A vector is a special type of array we need to use for this function, make sure to capitalize the first "V".
To access the data from the Vector variable now, we use: myvector.x, or y, or z.
These variables vary from the numbers -1.0 to 1.0, and so they use decimals.

So to do something like what you want, we might use something like this (on the actor we want moving in Draw Actor):

Code: Select all

// Declare our tilt variable.=
Vector tilt = getAccelerometer();

// The IF statements give us a "deadzone"
// so that tiny shakes when holding the device
// don't move it around

// Increase "0.2" for a bigger deadzone
if (tilt.y > 0.2)
{
    // This adds to the X value of our actor based
    // on how far we're tilting the device. Adjusting
    // the "10" will change how sensitive it is
    x = x + (tilt.y * 10);
}

// Decrease "-0.2" for a bigger deadzone
if (tilt.y < -0.2)
{
    // We use "ABS" to change the currently negative
    // value of "tilt.x" into a positive number,
    // easier to manage.
    x = x - (abs(tilt.y) * 10);
}


Of course, depending on what axis you want you'd change the tilt.y to something else. I'm not sure which axis is which on an iPhone, since I haven't had the chance to personally test it.

thanks DarkParadox.
I test it soon.
