Dynamic scale of Chr

Can you change the scale of a player dynamically?

I tried doing a player.matrix().scale(Vec (1,2,1)).. no effect..
tried setting it up in a preRender function also..

any suggestions?

Might be wrong about this, but I don't believe you can scale characters after creation. You will need to delete the player and use Game::World.objCreate to create a new player with a different scale.

I would prefer dynamic for sure... but even with this method - is it possible to scale by a Vec instead of float ( ie: non-uniform scale...) ?

I suppose so, but never tried. Game::World.objCreate has a matrix parameter, just change the scale of your matrix to be non-uniformed and see what happens.

Messed around with non-uniform scaling and got some odd results...

In all cases - object was scaled uniformly - acts like the .y,.z parm of the Vec is ignored..

Game::Obj *newObj = Game::World.objCreateNear(*obj,Matrix(Vec(5,1,1), sp ));
Object comes in scaled at x5 uniformly

Game::Obj *newObj = Game::World.objCreateNear(*obj,Matrix(Vec(1,5,1), sp ));
Object comes in scaled at x1 uniformly

Any ideas? ( thanks the pointers by the way!)

I just reread the header comments for objCreate/objCreateNear and noticed it says, "matrix scale will be used as objects scale." This is a clear sign as to why the y- and z-axis values are ignored (i.e. the matrix's scale value is equivalent to setting a value for Scale on an object via World Editor, it doesn't support non-uniform scaling).

However, it appears as if you can still draw objects using non-uniform scaling. For instance, this works:

Code:

void render()

{

   switch(Renderer())

   {

      case RM_PREPARE:

      {

         mesh.draw(Matrix3(Vec(10, 1, 1))); // draw using non-uniform scaling

      } break;

   }

}

Try setting the matrix again after objCreateNear or, if that doesn't work, perhaps this:

Code:

UInt Player::drawPrepare()

{

    SetMatrix(m); // set non-uniform scaling

    UInt modes = super::drawPrepare(); // draw character

    SetMatrix(); // clear matrix

    return modes;

}

hmm. i'll experiment with this - wondering if it would cause some issues with objects rendering differently than how they react to physics tho...

Game::Chr and CSkeleton do not support dynamic rescaling

you could do it by having Game::Chr sources (company license), and apply manual modifications to sources
