Make the pawn look at the cursor (sidescroll)

[rXp]

Hello,

I am making a 2D sidescroller game (to learn the basics of UnrealScript) and the camera is setup and the pawn moves like I want.
But I want it to aim at the cursor, my cursor is defined by 3d vector and already displayed on the screen.
So now I need to find the delta of the pich and yaw but I don't now how to achieve that because I don't know what function I can use to direct the aim.
What can i do ?

Best regards,

I think I've done something similar once.
Take a look at what I did in this post.

There's also a Youtube-clip showing my results - see if it's what you want.

Seeing the video, yes that is what I'm looking for Thank you a lot
And I see that our code are think the same way so the changes are extremely little !
Thank you a lot

The code seems correct but the mouse coordinate seems wrong.
The issue is that that the mouse should be in the center (x and y axis) of the screen for the pawn to turn BUT the cursor think he is at the center way before the actual center.
Screenshot :
And the only change made on the actual position is this one :

event PlayerInput(float DeltaTime)
{

// Add the aMouseX to the mouse position and clamp it within the viewport width
mousePosition.X = Clamp(mousePosition.X + aMouseX, 0, 1920);
// Add the aMouseY to the mouse position and clamp it within the viewport height
mousePosition.Y = Clamp(mousePosition.Y - aMouseY, 0, 1080);
super.PlayerInput(DeltaTime);
}

Do you have an idea ?

[EDIT] I found the issue, the cursor had a wrong position but the position calculated was good.
But I see that the cursor is not always where the player shoot :s

Hm, that's not good

Is there a big difference between the cursor and the actual aiming?
Have you noticed any specific incorrect behaviour? For example; 'only when aiming to the left'.
If it's just a few degrees, it could be that you just have to adjust the aim by the crosshair's textureheight and width.

The first was about that (drawtile). But now the more i look down the more it is incorrect (the crosshair gets too low).
I calcule the angle with an atan2 of the direction vector (the one that is created by (crosshair2DPos-player2DPos) and add or not pi/2 for the right side , what is wrong ?

Thanks for pointing this out
It took a while for me to find the problem, but I managed to fix it eventually.

I don't know whether you still have this problem or not, but if you do; you can check out my new code in the same old thread: http://forums.epicgames.com/threads/...1#post30115814

To summarize:
The problem was I was using the player's 2D-projected position to calculate the aim, while I should have been using the weapon-socket.
If you fix that, the offset should disappear.
