Problem with the playerController

[Julio Jerez]

Oh my bug, it is fie now please sync and try again.

did you set the origin of your playe at the lower bottom?

[Neo]

Sure, now the front direction is ok. But unforturnately, I failed to find the way to change the origin in irrlicht...

[Julio Jerez]

where is the origon in irrlitch model?
My impresion was that is was the lowere bottom.

Somewhere near the center, Despite how you model it in the 3dmax.

[Julio Jerez]

did that changed? it use to be that the oriogin was at the lower botton.

It does not matter the engine supports that
I will add a function to the controller like SetOrigin(vector origin)
and that will solved it

[Neo]

I searched the irrlicht forum, found that in irrlicht, the origin can not be changed since loaded into engine..
But do something when modeling could change it, in fact , my player did stand on land in the 3ds max(the lower part is nearly 0),
but when it is loaded into engine everything changed, I have no idea about how does irr set the origine..
Anyway, thx Julio.


Well, How about controller collision problem? Can a player block a dynamic body now?

[Julio Jerez]

I will solve both those problem over the weekend.
The origin first because it is eassier

if the orgin of a model in irrlict is not agt the bottom then Irrlitch must have a function to ge that origin.
how were you setting the origin before, can you post the code fragment that you were using?

[Neo]

irr set the origin automatically
All I have to do is use the getMesh() interface
somthing like:

Code: Select all

irrMesh* mesh=videoDriver->getMesh(filename);
IrrSceneNode node*=SceneManager->addSceneNoe(Mesh);


There's no function for me to set or get the origin..Or maybe I can ask them on the irr forum..

[Julio Jerez]

how do you get teh dimation of teh collision shape?
or is there away to get the boudning box.

when you were using core 200, whow me the code you were using to initalize teh playe controller.
In the code there must be the way to ge the offset matrix for the collision shape?


In any case do not worry, when I add the function set origin,
the you can call it and set the orign to be at the cente of the BBox, and the will be the same as if we with core 200.
I will add that tonight.

[Neo]

Yeah, there's a a way to get bounding box
just call

Code: Select all

aabbox3d bbox=object->getTrasformedBoundingBox

Then it will return a object which contain the information of bounding box ,and you can then call the

Code: Select all

bbox->getExtent();

It will return a vector which contains the dimension information.
And in the core 200, I use this vector to create newton collision shape.

[Julio Jerez]

Ok now there is a function for offseting teh playe origin. teh default is still teh lower bottom bu you cna call that funtion to change the origin
here is teh example

Code: Select all

      // now make a simple player controller,
      dMatrix playerAxis;
      playerAxis[0] = dVector (0.0f, 1.0f, 0.0f, 0.0f); // the y axis is the character up vector
      playerAxis[1] = dVector (1.0f, 0.0f, 0.0f, 0.0f); // the x axis is the character front direction
      playerAxis[2] = playerAxis[0] * playerAxis[1];
      playerAxis[3] = dVector (0.0f, 0.0f, 0.0f, 1.0f);

      // make the player controller, this function makes a kinematic body
      m_controller = manager->CreatePlayer(radius, radius * 0.5f, height, height * 0.33f, playerAxis);

      // player by default have the origin at the the center of the lower bottom of the collision shape.
      // you can change this by calling SetPlayerOrigin, for example if a player has it origin at the center of the AABB you can call
      m_controller->SetPlayerOrigin (height * 0.5f);

Is it normal, that the player body doesnt collide with objects wich connect by joints? I have a door with a custom hinge joint and the player just walk trhough the door without affect them. Is this the same problem you're working on? Without the joint everything is working fine.

[Julio Jerez]

I should collide with every object, that is probleby a bug but let me figure ou the dll bug first.

Hi. After a long time I'm back to PlayerController.
1. What is the different between BasicPlayerController and AdvancedPlayerController? I can only notice that the Scene is different.
2. The problem with the HingeJoint is still there. If I want to change to AdvancedPlayerController what must I cange?

Thank you.

[Julio Jerez]

the advance player controller and the basic are the same, but the advance use triggers to interact with object in the scene.
what si the problem with hinges?
