Raycast - What did I click on?

rstralberg · 05-24-2015 07:43 PM

I use this code below to check where I click with the mouse on something

Code:

Vec pos; 

      Vec dir;      

      ScreenToPosDir(Ms.pos(), pos, dir); 

      pos.z += 0.6; // we need to be outside our own mesh

      // test if we hit anything

      PhysHit phys_hit;

      if( Physics.ray(pos, dir*D.viewRange(), &phys_hit) ) 

      {

          // Clicked on something, but what???

      }

      else

      {

         // Clicked on 'nothing'

      }

Now I want to check if I clicked on the on the World Part mesh or not.
Later on I will also need to know which object I clicked on if any.

Any suggestions?

Code:

AG_DEFAULT=0, // default group for all actors

   // user defined groups should be in the range of 1..15

   AG_DOOR      =29, // Game::Door

   AG_CONTROLLER=30, // Controller

   AG_TERRAIN   =31, // Game::World Terrain

   AG_NUM       =32, // number of actor groups

phys_hit.group()
Uses IndexToFlag(AG_TERRAIN)
if you want to specifically target only a certain group of objects

Then there is object type
phys_hit.obj->type()

Then you got the cast.
PhysHit phys_hit;
if(NPC *npc = CAST(NPC, phys_hit.obj)){
//object is of NPC
}
