Does OnMouseUp() require OnMouseDown() to be triggered first?
This might be a bug, or I may just be looking at this wrong, but here's the behavior I'm seeing. I want to be able to click the mouse somewhere on the screen (not over my target) and drag the mouse over the target object. When I let go of the mouse button, I'd like things to happen. On my target object I have a script attached with this:
function OnMouseUp() {
print("Your Mouse button is up!");
}
Pretty simple. Yet, when I click somewhere on the screen, drag my mouse on top of the object, and then let the button go nothing happens. If I click the mouse down on top of my target and then let it go it works correctly. I assume this is because when my mouse is clicked while over the target it fires the OnMouseDown() function.
I've worked around the issue by setting a variable to true when OnMouseEnter() is triggered, and then in the update() I test is the variable is true && the GetMouseButtonUp(0).
function OnMouseEnter() { mouseIsOver = true; }
function Update() { if(mouseIsOver) { if(Input.GetMouseButtonUp(0)) { print("Your mouse button is up!"); } } }
Is this a bug, or am I missing something really obvious?
From the documentation:
"OnMouseUp is only called if the mouse was pressed down while over the same GUIElement or Collider."
http://unity3d.com/support/documentation/ScriptReference/MonoBehaviour.OnMouseUp.html
So perhaps it's because you're moving the mouse before releasing the mouse button that you're not getting the expected behavior?
I figured the answer was right in front of me! Guess my reading comprehension isn't what it used to be!
If this doesn't work for you, you need to code a custom raycast or detection inside of Update(), with GetButtonUp("mouse 0"). This will work no matter what, but you need to check if the cursor is over the object you want.
