Getting Last Player Rotation (theRotationOfMovingTheMouse) from an input to input

[Neongho]

So i want to get the last x and y vector that player did move from the mouse , from when i Pressed the left mouse button from when i released it.


I have no idea from where to start , what variables to touch , what vars store arleady that info , how do i capture that mouse input , the x and y

also then after that i want to get if it was

a Up movement ( user moved mouse up )
a Down movement ( user moved mouse up )
a Rightmovement ( user moved mouse up ) a
Left movement ( user moved mouse up ) a

I have no idea on how i would process the mouse input x and y to assign that variables with a control statement

if...

Should i use vectors?






Help !

Here is one way to do it in an extended PlayerController, should get you started...

event PlayerTick( float DeltaTime )
{
	local vector mouseVect, upVect, rightVect;

	upVect = vect(0,1,0); // (not sure up is positive for mouse stuff)
	rightVect = vect(1,0,0);  // (not sure right is positive for mouse stuff)
	

	mouseVect = vect(PlayerInput.aMouseX, PlayerInput.aMouseY, 0);

	if (mouseVect dot upVect > 0)
	{
		// mouse was moved up
	}
	else if (mouseVect dot upVect < 0)
	{
		// mouse was moved down
	}
	if (mouseVect dot rightVect > 0)
	{
		// mouse was moved right
	}
	else if (mouseVect dot rightVect < 0)
	{
		// mouse was moved left
	}

	super.PlayerTick(DeltaTime);
}

I get error line 16 error missing compnent x of vector ?? -> mouseVect = vect(PlayerInput.aMouseX, PlayerInput.aMouseY, 0);


What does the KeyWord vect???

What does that dot betwwen those inputs??? function?

Is there Anyway to convert a negative number in the code in positive nubmer , if i know that i can get it : ) ;

 //captureMouseInput
event PlayerTick( float DeltaTime )
{


    Local float Right;
    Local float Left;
    Local float Up;
    Local float Down;


      WorldInfo.game.Broadcast(self,LastMouseInput);

	if (PlayerInput.aMouseX > 0)
	{

	   Right=PlayerInput.aMouseX;
       left=0;


	}
	if (PlayerInput.aMouseX < 0)
	{
    left=Abs(PlayerInput.aMouseX);
    Right=0;
	}



	//wich one wins

	if(Right>left)
	{
	 LastMouseInput="Right";
    }

    if(Left>Right)
	{
	 LastMouseInput="Left";
    }






    WorldInfo.game.Broadcast(self,LastMouseInput);



    super.PlayerTick(DeltaTime);


}

this works, next time i'll search object for this matehmaticall things , sorry , didn't know where exacly to look for
