THREE.js Particle engine

[lenacus]

Hi everybody,

 

I have read many tutorials and I start programming with this assistance. Despite this help, I can't make the engine run properly particles. 

 

I have a ship. Currently, it has 1 "reactor" at 0,0,0 and it works very well (view my upload 3.jpg). The SPE is linked with the scene :

 

                reactorGroup = new SPE.Group({                    texture: THREE.ImageUtils.loadTexture('./img/smokeparticle.png'),                    maxAge: 1                });                reactorEmitter = new SPE.Emitter({                    type: 'cube',                    position: ship.position,                    positionSpread: new THREE.Vector3(1, 1, 1),                    sizeStart: 2,                    sizeEnd: 1,                    colorStart: new THREE.Color( 'white' ),                    colorMiddle: new THREE.Color( 'red' ),                    colorEnd: new THREE.Color( 'blue' ),                    opacityStart: 0.05,                    opacityMiddle: 1,                    opacityEnd: 0,                    particleCount: 1000                });						reactorGroup.addEmitter(reactorEmitter);		scene.add( reactorGroup.mesh );

 

Now I would like to shift the engine on the x axis and y (view my upload 4.jpg).

 

If I attach the particles to the scene, the position is incorrect when moving (view my upload 1.jpg). 

 

So the problem is that if I attach the particles to the ship with  ship.add( reactorGroup.mesh ); the particle has no effect. And if I attach the particles to the scene, the position is incorrect when moving. 

 

 

Can you help me please ?

thanks.
