Random "RAYCASTING failed to find ray" error

[Shando]

Hi All,

I'm trying to get a UI to appear when the FPS Player walks into the bounds of an AI Sensor attached to a model (Sinbad seems to work fine, but Jaiqua and Ninja have this error).

The error I'm getting is:

Code: Select all

ERROR::RAYCASTING failed to find ray
LUA ERROR: Entity ID [ -1 ] was not found or it is invalid?


This error happens *most* of the time, but not always??

The code I'm using is:

Code: Select all

objJ = 0
bSensorJ = false;

function onInit ( objID )
   objJ = objID;
   sensor.enableVisibilityCheck ( objJ, 1 );
   anim.setEnabled ( objJ, "Walk", 1);
   anim.setLooped ( objJ, "Walk", 1 );
   anim.playAnimation ( objJ, "Walk", 0, 0);
end

function onSensorContact_Stay ( targetID, distance )
   if ( not bSensorJ ) then
      local sTgt = entity.getTagFromID ( targetID );

      if ( sTgt == "Player" ) then
         local isVisible = sensor.isTargetVisible ( objJ );

         if ( isVisible == 1 ) then
            if ( distance < 5 ) then
               bSensorJ = true;

               local tmpTalk = tonumber ( sky.getVar ( "talking" ) );

               if ( tmpTalk == 0 ) then
                  entity.lookatObject ( objJ, targetID, 1, 0, 0, 1 );

                  gui.show ( "Chat_HUD", "textCell9" );
                  gui.setText ( "Chat_HUD", "lbl_talk_C", "Press E to talk" );
                  sky.setVar ( "talking", 1 );
                  sky.setVar ( "talkingto", objJ );
               end
            end
         end
      end
   end
end


which is almost identical for Sinbad, Jaiqua & Ninja.

Any help would be greatly appreciated.

i not following as much as there is no raycast in that code? Plus looking at that code i cannot see any errors.

Perhaps the error is outside of the code. The way i found the previous error was commenting out most of the code and slowly add things back into play until it stops working.

Is the error from the FPS player or from the other NPC's.

I will have a look in the scene files as well to see if i can find a problem.

Edit: The first time i ran it, both the ninja and jaiqua picked up the chat. Then the second time they stopped working and threw that raycast error.

Also, my mistake and i understand what you are meaning now with the raycast.

Edit2: The error appears when entering the AI Sensors

Edit3: I am now looking in the sensor as i think the error is internal at the moment

So it turns out that this is due to the Raycast being stored with the sensor is being cleared off when the game stops. This is because you enabled the visibilty Check in code i believe. Normally this wouldn't happen.
But i managed to figure out why it was happening and now i have to hunt why the ninja is not displaying.

Have you tried working without this:

Code: Select all

sensor.enableVisibilityCheck ( objJ, 1 );

for now to continue until the next patch

I believe this feature is too only retrieve the id when the character is in visible sight and say not behind a wall.

I have found out the reason why the ninja doesnt work where the Jaiqua does.

Code: Select all

Line 30: entity.lookatObject ( objS, targetID, 1, 0, 0, 1 );

The "objS" doesnt exist and needs to be "objN".

This will then work with the previous fix for you to continue for now until the next release. You will then be able to use the visibility check.

Hi SP,

Thanks for all this

I'll get rid of the "enableVisibilityCheck" for now, it's only for a demo, so shouldn't cause too many issues.

The "objS" doesnt exist and needs to be "objN".

aaggghhhh!!!! I even checked for exactly this twice and still managed to miss one That'll teach me to copy and paste!!!!
