Crosshair in 3D

DreamsInHD · 11-19-2015 08:44 PM

Hi,

How do i make a crosshair in a 3D top down shooter? The crosshair is 2D and should be
where the cursor is, while the camera hovers over a player. When i press leftclick
the player should shoot in the direction of the crosshair, but i'm having some trouble showing the crosshair at the position of my cursor since it's 2D and the game in 3D.
Any suggestions?

Thanks in advance.

You probably want billboarding functionality, so there is the Image method draw3D for simple usage.
Otherwise if you want more control, in Draw() you might wanna do something like...

Code:

Vec myPos = Vec(0, 0, 0);

   ImagePtr loo = UID(609788035, 1305964377, 3078217115, 66910196);

   VI.image(loo());   

   //VI.image(Images(UID(609788035, 1305964377, 3078217115, 66910196)));

   Vtx3DTexCol v[4];

   v[0].tex = Vec2(0, 1);

   v[1].tex = Vec2(0, 0);

   v[2].tex = Vec2(1, 0);

   v[3].tex = Vec2(1, 1);            

   REPAO(v).color = Color(255, 255, 255, 255);

   v[0].pos = myPos;

   v[1].pos = myPos + Vec(0, 1, 0);

   v[2].pos = myPos + Vec(1, 1, 0);

   v[3].pos = myPos + Vec(1, 0, 0);            

   VI.alphaTest(false);

   VI.color(Color(255, 255, 255, 255));

   VI.face(v[0], v[1], v[2], v[3]);

   VI.end();

In general search for caps "VI" in the code.
