Objects under cursor - AI : Game::Chr

Ogniok · 04-11-2010 07:21 PM

Hi!

I have struct AI in my game. It comes from Game::Chr. I want to do something when AI obj is under cursor. I use this code but it didn't work:

Code:

//Get object under cursor

         Game::Obj *objectUnderCursor;

         objectUnderCursor = NULL;

         Vec pos, dir;

         ScreenToPosDir(Vec2(0, 0), pos, dir);

         PhysHit phys_hit;

         if(Physics.ray(pos, dir * D.viewRange(), &phys_hit, ~IndexToFlag(AG_CONTROLLER))) objectUnderCursor = phys_hit.obj;

         //Detect type of object which player want to interact

         if(AI *interactObject = CAST(AI, objectUnderCursor))

                 {

                 }

Debugger show that objectUnderCursor is empty all the time.

~IndexToFlag -> IndexToFlag ?

I've changed to this:

Code:

if(Physics.ray(pos, dir * D.viewRange(), &phys_hit, ~IndexToFlag(AG_CONTROLLER))) objectUnderCursor = phys_hit.obj;

but then objectUnderCursor = Player

Your current mouse position check is Vec2(0, 0) set it to Ms.pos and you will have more success.

Code:

Game::Obj *objectUnderCursor;

Vec screen_pos, screen_dir;

ScreenToPosDir(Ms.pos, screen_pos, screen_dir);

Vec start = screen_pos;

Vec end = screen_pos + screen_dir * D.viewRange();

PhysHit phys_hit;

if(Physics.ray( start, end - start, &phys_hit, ~IndexToFlag(AG_CONTROLLER)))

{

     objectUnderCursor = phys_hit.obj;

}

I know that my mouse position is Vec2(0, 0) because this is crosshair in my game. Mouse isn't visible. I try your code but it didn't work.

If you run only:

if(Physics.ray( start, end - start, &phys_hit))

Do you get any valid object on phys_hit.obj ?

All interactions work but interaction with AI don't work.

Code:

if(Ms.b(0) && timeToAction <= 0)

      {

         //Get object under cursor

         Game::Obj *objectUnderCursor = NULL;

         Vec pos, dir;

         ScreenToPosDir(Vec2(0, 0), pos, dir);

         PhysHit phys_hit;

         if(Physics.ray(pos, dir * D.viewRange(), &phys_hit, IndexToFlag(AG_CONTROLLER))) objectUnderCursor = phys_hit.obj;

         //Detect type of object which player want to interact

         if(Tree *interactObject = CAST(Tree, objectUnderCursor)) //WORKS

         { 

                         //tree interaction code - WORKS

         }//end if(Tree * interactObject = CAST...

         else if(AI *interactObject = CAST(AI, objectUnderCursor)) //DOESN'T WORK

         {

             //open dialogue with Character //DOESN'T WORK

         }

         else //WORKS

         {

            //attack code... //WORKS

         }//end else

      }//end if(Ms.b(0) && timeToAction <= 0)

Only interaction with AI don't work so problem is in AI class

I noticed Phys hits AI if it's died it's after call ragdollEnable() function in AI class.

If AI Died(ragdollEnable)
Phys works
Else
Don't work

The problem is resolved! In AI::Create() we added

Code:

T.ctrl.actor.group(31);

and it helped

I've actually replicated your technique it seems and I have a:

if(Interactable *interactObject = CAST(Interactable, objectUnderCursor))

but it always returns false and breaks off there. Any ideas what might be wrong? Everything else is pretty much the same as yours.

Ogniok · 05-10-2010 09:45 AM

Did you set mode of objects with OBJ_TYPE Interactable to default? And did you set container for this objects in game?

Bah, every time I write something on here, I fix it myself.
