Delete / Create Objects in Editor Code

Gian-Reto · 02-14-2013 06:17 PM

I'm trying to modify my custom Editor mode so that I can place Terrain Objects automatically from code.

Is there any good tutorial about the proper way to delete / add objects like in the editor, but from code (with heightmap aligning, random angle and so on)?

Can I use the tutorials for the Ingame Objects deletion / creation?

Thanks in advance for any help

Hi,

did you check at World Editor's methods:

void objDelete( ); // delete selected objects
void objCreate(C Vec &pos, Game::ObjParams *force_params=NULL); // create object at 'pos' world position, 'force_params'=if create object from custom parameters (if set to NULL, then it will be set according to current object selection)

Hi Esenthel

No I didn't... somehow didn't found them. I'll try it out immediatly.

Thanks in advance

Okay, it seems I still do something wrong.

What I try to at the moment is clearing my world from all embeded objects to automatically place them in a second step.

To achieve that I loop trough all areas, selecting all the embeded objects and deleting them:

Code:

void cleanTerrainObjects () {

    for (Int iteratorTX = -32; iteratorTX <= 32; iteratorTX++) {

        for (Int iteratorTY = -32; iteratorTY <= 32; iteratorTY++) {

            Edit::Area *area = Edit::World.grid.get(VecI2(iteratorTX,iteratorTY))->data();

            for (Int i = area->objs()-1; i >= 0; i--) {

                Edit::Obj obj = area->obj(i);

                if (obj.access() == Game::ACCESS_EMBED) {

                    area->setChanged();        

                    Edit::World.objSelSelect(&obj);

                    Edit::World.objDelete();

                    area->hmChanged();

                }

            }

        }

    }

}

I get an Exception in "EditStateUpdate" it seems. It happens after the code above has run and the Method it is in has ended (this Method gets called by the method bound to a button in the custom edit mode, but this Method is empty besides the Method call at the moment).

I assume some of the code written above must somehow cause this.... because the Exception happens at the end of the calling MEthod, and no other code is in it.

Anyway, one step further.

EDIT:

Got it working after some debugging. I'm not 100% why the first version didn't work, but being the C++ noob and Java-Code-Monkey that I am, I probably did something really stupid when I assigned the object. Pointers, oh the horror! wink

Code:

void cleanTerrainObjects () {

    for (Int iteratorTX = -32; iteratorTX <= 32; iteratorTX++) {

        for (Int iteratorTY = -32; iteratorTY <= 32; iteratorTY++) {

            Edit::Area *area = Edit::World.grid.get(VecI2(iteratorTX,iteratorTY))->data();

            for (Int i = area->objs()-1; i >= 0; i--) {

                //Edit::Obj foundObject = area->obj(i);

                if (area->obj(i).access() == Game::ACCESS_EMBED) {

                    area->setChanged();        

                    Edit::World.objSelSelect(&area->obj(i));

                    Edit::World.objDelete();

                    area->hmChanged();

                }

            }

        }

    }

}

Now onwards to creating the objects...
