1  Java Game APIs & Engines / Java 3D / GeometryArray help!! on: 2004-10-31 11:07:08
I want get tow PointArray of the Geometry at different position.

But I always get the same PointArray at different Position.

Here is parts of my program:

//I use PositionInterpolator to move the Geometry via x axis.
//and I have get the Geometry.

Geometry g = myShape.getGeometry(); //myShape is a shape3D from the .obj file

Point3f[] p3f1 = new Point3f[ 360 ];
for( int i = 0; i < 360; i ++ )
{
p3f1[ i ] = new Point3f();
}

if( g instanceof GeometryArray )
{
( ( GeometryArray ) g ).getCoordinates( 0, p3f1 );
}

//Now I'm getting tow PointArray

Point3f[] pArray1 = new Point3f[ 360 ];
Point3f[] pArray2 = new Point3f[ 360 ];

for( int i = 0; i < 306; i ++ )
{
pArray1[ i ] = p3f1[ i ];
pArray1[ i ].x = 0.2f; //set PointArray at the start position of the PositionInterpolator

pArray2[ i ] = p3f1[ i ]; //get the PointArray during the moving

}

But When I change pArray1[ i ].x, the pArray2[ i ].x also changed and it also equals 0.2f.

What problem I have met?
How to solve it?

thanks!
2  Java Game APIs & Engines / Java 3D / Help for CollisionBounds!!! on: 2004-10-11 12:11:10
When I load a OBJ file,I can get a BranchGroup  or a Shape3D of the OBJ file.When I use the method getBounds(),it returns a bounds box.But th OBJ file is an abnormity geometry.I want set this bounds as BranchGroup's CollisionBounds.how can I get the exact bounds of this specify OBJ file?

Add your game by posting it in the WIP section,
or publish it in Showcase.
