My application is already setup to the Camera Vector2 so all I need is the code to move it. I can move it with the keyboard already, I just want to move it with the right mouse click/drag method.

If anyone can help, that would be great.

Thanks,

Dro Sarhadian :)

When you first click right you have to get the position of the mouse and store it in a Vector2. In the next frame you again get the mouse position and store it in a nother value. To get the actual movement you now have to substract LastPosition -  CurrentPosition and just add the result to the camera position. At the end of the frame you set the LastPosition equal the CurrentPosition.

Thanks, I'll try this in a little bit.

I tried to do what you said, but I got stuck.

Here is the current code that I have so far:

I don't know what to do now. Am I doing everything right or am I doing something wrong.

Can you please help me?

Try "CameraPosition += currentPosition - lastPos;"

See when you subtract currentPosition - lastPos, you get a vector that tells you how much the mouse moved.  By adding that to the camera's position, you move the camera by the amount that the mouse has moved (and in the same direction of movement).

MJP:

Try "CameraPosition += currentPosition - lastPos;"

Doesn't seem to work. I changed that line to told me to change but it didn't work. Am I doing everything right? Is the code correct? I'm not sure if the code is correct and how to fix it. Would I go add mouse support like I do to game pad support or what? I'm gonna try some different types of code and see what happens. Also, does the code goes in the Draw method correct, since I'm using the WinForms sample from this site (Not the content manager one)?

Hmm ...

Try this code, but the only realy thing I've changed was the lastMouse = currentMouse at the end (and that using Microsoft ... but thats just a hint if you need the ButtonState more often then once)

I already used that sample once too (for a editor), and had too my problems.

About that code now, I don't thing that the bug is in that code, its may how you use it:

Is the Vector3 you use for the view matrix the same as in that code? Do you set lastMouse = currentMouse somewhere else in the code?

If its non of those things, could you post the whole draw method?
