Mesh to follow a path/curve

[Metalx1000 4]

So I wrote this little script that has a Cube move from one empty to another to make it's way through a maze to another Cube.

My question is, Can a get an object to follow a path/curve?

I've tried Googling "babylonjs follow path", but didn't find anything.

Is this possible at this point?
Am I using the wrong wording in my searching?

 

Thanks for any help.

It would be a good idea to define paths using bezier curves. This is quite powerfull, theres a tutorial. http://devmag.org.za/2011/04/05/bzier-curves-a-tutorial/

Kilombo,

So what you are saying is that there is currently no function in Babylonjs (as far as you know) that does this and if I want to do it I'll have to write my own function. 
Is that correct?

[Deltakosh 4315]

Correct. But check our roadmap, we have this point on it:)

Hi Metal. I'm kind of a newbie on this, but has far has i know, there isn't, anyway.... It's quite easy to implement. I'll pass you the code I implemented in opengl 2 years ago, you just have to adapt to javascript.

//varáveis da curva de besierGLfloat ctrlpoints[4][3] = {	{ 12000.0, 0.0, 0.0}, { 17000.0, 0.0, -12800.0}, 	{-9000.0, 0.0, 0.0}, {12000.0, 0.0, 0.0}};GLfloat besx,besy,besz;float tempo = 0.0f;//Calculo de cruva de beziervoid calculatePoly(float t){		 int i=1;		 float a = -t*t*t + 3*t*t - 3*t + 1;		 float b = 3*t*t*t + -6*t*t + 3*t;		 float c = -3*t*t*t + 3*t*t;		 float d = t*t*t;		 besx = (ctrlpoints[i-1][0]*a + ctrlpoints[i][0]*b + ctrlpoints[i+1][0]*c + ctrlpoints[i+2][0]*d);		 besy = (ctrlpoints[i-1][1]*a + ctrlpoints[i][1]*b + ctrlpoints[i+1][1]*c + ctrlpoints[i+2][1]*d);		 besz = (ctrlpoints[i-1][2]*a + ctrlpoints[i][2]*b + ctrlpoints[i+1][2]*c + ctrlpoints[i+2][2]*d);	}desenhaObj(2,besx,besy,besz,rotacao,3);

The "desenhaobj" method receives has args the number of the mesh, besier position x, and so on, rotation (calcultated in another place) and the size of the mesh.

 

Hope I've been helpfull.

Deltakosh, good to hear.

Kilombo, thanks for the help.  I'll play around with this.

Personnally I used TweenLite and TimelineLite to move my BabylonJs camera.  There is a cool bezier plugin.

Look at this example which inspired me http://codepen.io/GreenSock/pen/zcmpo.

It was done with tweenMax which is'nt free but bezier plugin work also with tweenLite (free version).

Here is a little demo for you.
