Input.GetKeyUp Don't work to detect release of key
I have searched and seen several answers, but i cant get it to work. The code wont print the button up message, so i assume that i am missing something.
I am trying to make a function for Interaction and when you release the button it should confirm your choice of action. Similar to a weapon selection wheel.
Update
void Update()
{
switch (isAiUnit)
{
case true:
{
AiInput();
}
break;
case false:
{
PlayerInput();
}
break;
}
}
void PlayerInput()
{
if(Input.GetKey(KeyCode.E))
{
if(Input.GetKeyDown(KeyCode.E))
{
interactionTimeStart = Time.time;
}
InteractionInput(interactionTimeStart);
}
}
void InteractionInput(float timeStart)
{
Debug.Log(" Button Down " + (Time.time - timeStart));
if (Input.GetKeyUp(KeyCode.E) && ((Time.time - timeStart) > 0.25f))
{
Debug.Log(" ButtonUp ");
}
}
In your check you are using & which is a bitwise operator, use && instead.
Ok with that the next step I would try is removing the Time.time - timeStart just to check if it's actually KeyUp that's an issue. Though looking again, InteractionInput is being called during GetKey, this most likely will never work since GetKeyUp is only true on the frame the key was released and if the frame reads GetKey I don't believe it will get the key co$$anonymous$$g up in the same frame. Something you could test is change the key for GetKeyUp and see if it triggers while holding e
Try this:
void PlayerInput()
{
if(Input.GetKeyDown(KeyCode.E))
{
interactionTimeStart = Time.time;
}
else if (Input.GetKeyUp(KeyCode.E))
{
InteractionInput(interactionTimeStart);
}
}
then
void InteractionInput(float timeStart)
{
Debug.Log(" Button Down " + (Time.time - timeStart));
if (Time.time - timeStart) > 0.25f)
{
Debug.Log(" ButtonUp ");
}
}
You are calling InteractionInput() from inside of the brackets around if(Input.GetKey()). On the frame that the button is released, however, Input.GetKey() will be false so InteractionInput() will never be called. You need to check for GetKeyUp outside of GetKey
