所以我写了这个由左侧魔杖上的触控板控制的径向菜单。它通过我的手指在触控板上的位置确定要放大哪个按钮。
奇怪的动作可以在这里看到。
在这里,我攻击了与此问题相关的代码,即左魔杖的代码。
SteamVR_TrackedObject obj; //The wand
public GameObject buttonHolder; //All the buttons will be children of this object
public bool buttonEnabled;
void Awake() {
obj = GetComponent<SteamVR_TrackedObject>(); //this will be left hand controller
}
void Update() {
var device = SteamVR_Controller.Input((int)obj.index);
//if touchpad touched
if (device.GetTouch(SteamVR_Controller.ButtonMask.Touchpad))
{
if (buttonEnabled) //if radial menu is open
{
//touchPadAngle: Get the angle between touch coord and X-axis
Vector2 touchedCoord = device.GetAxis(EVRButtonId.k_EButton_Axis0); //what is this line each variable
float touchPadAngle = VectorAngle(new Vector2(1, 0), touchedCoord); //(1, 0) is X-axis
// ------------------- Find closest button ------------------------
//Description: The process will be done by calculating the angle between button_Vector2 and X-axis (button_V2_to_10)
// And then find the button with the closest angler difference with (touchPadAngle).
float minAngle = float.PositiveInfinity;
Transform minButton = transform; //Temperatry assign wand tranform to it.
float pad_N_button_Angle = 0.0f; //Angle between touchPadAngle and buttonAngle.
Vector2 button_V2_to_10;
float button_Angle;
foreach (Transform bt in buttonHolder.transform)
{
button_V2_to_10 = new Vector2(transform.position.x, transform.position.z) - new Vector2(bt.position.x, bt.position.z);
button_Angle = VectorAngle(new Vector2(1, 0), button_V2_to_10);
pad_N_button_Angle = Mathf.Abs(button_Angle - touchPadAngle);
//Both buttonAngle and touchPadAngle range from -180 to 180, avoid Abs(170 - (-170)) = 340
pad_N_button_Angle = (pad_N_button_Angle > 180) ? Mathf.Abs(pad_N_button_Angle - 360) : pad_N_button_Angle;
if (pad_N_button_Angle < minAngle)
{
minButton = bt;
minAngle = pad_N_button_Angle;
}
}
//Magnify the closest button
foreach (Transform bt in buttonHolder.transform)
{
GameObject btGO = bt.gameObject;
if (!btGO.GetComponentInChildren<ButtomHandler>().onHover && bt == minButton) {
//Magnify
}
else if (bt != minButton && btGO.GetComponentInChildren<ButtomHandler>().onHover)
{
//minify
}
}
}
else {
activateButtonMenu();
}
}
//dis-hover all button if leave touch pad
if (device.GetTouchUp(SteamVR_Controller.ButtonMask.Touchpad)) {
//Hover the closest button
foreach (Transform bt in buttonHolder.transform)
{
GameObject btGO = bt.gameObject;
if (btGO.GetComponentInChildren<ButtomHandler>().onHover)
{
//minify
}
}
}
我被困在这里,任何帮助将不胜感激
