if win8_device_touchscreen_available()
{
vk[2] = virtual_key_add(32, display_get_height()
- 128, 64, 64, vk_left);
vk[1] = virtual_key_add(128, display_get_height()
- 128, 64, 64, vk_right);
vk[0] = virtual_key_add(display_get_width() - 96,
display_get_height() - 128, 64, 64, vk_up);
}
The above code will check for touch screen availability and if it is enabled, create three virtual keys.
