hey guys

im using plains for some things in the program i am writing and i have this strange problem. I create a plain and texture it which works fine, then I want to instance it several times and every copy only shows up as half a plain. I tried using clone with the same results.

any ideas?

Check out the screenshot to see what I mean.

Can you make the code availiable ? And do you scale the planes ?

no scaling, the code is as follows:

+ Code Snippet

//private member function
void build()	{
                //get empty resource ids
		if (resnum == 0)	{
			resnum = getresnum();
			objnum = getobjnum();

			dbLoadImage("media/GUI/text_box.jpg", resnum);
			dbMakeObjectPlane(objnum, (float)xsize / (float)dbScreenWidth(), (float)ysize / (float)dbScreenHeight());
			dbTextureObject(objnum, resnum);

			myobjnum = objnum;
		}	else	{
			myobjnum = getobjnum();
			dbInstanceObject(myobjnum, objnum);
		}

		dbLockObjectOn(myobjnum);
		dbSetObjectLight(myobjnum, 0);
		dbSetObjectFilter(myobjnum, 0);
		dbPositionObject(myobjnum, float((float)(xpos-50)/100.0f), float((float)(ypos-50)/83.0f)*-1, 1);

		dbHideObject(myobjnum);
	}

I would rather not post the whole class but I will if necessary

Certainly nothing dodgy looking there. Will have to try a standard instance call later on...

However, it does appear that when an object is instance'd, the copy is flipped horizontally :

+ Code Snippet

void DarkSDK()
{
	dbLoadImage("C:\\MOO.BMP",1);
	dbMakeObjectPlane(1, 25.0,27.0);
	dbTextureObject(1,1);
	dbPositionObject(1,0.0,0.0,0.0);
	dbInstanceObject(2,1);
	dbPositionObject(2,30.0,0.0,0.0);
	dbPositionCamera(0.0,30.0,-70.0);
	while ( LoopSDK ( ) )
	{
		if ( dbEscapeKey ( ) )
		{
			return;
		}

		dbSync ( );
	}
}

hmm im pretty sure that only applies for the first instance, cause when i instance it multiple times it works fine on all the others. and when i rotate the first instance, its still half...
