Black particle, slow the time and physic links

[The Snow Irbix]

Hello guys !

I need again a little bit of help,

I love babylonJS and his community, you are awesome guys !

 

Firstly, I would like to use blacks particles, but I don't know how can I do this, because it's the transparent color.

 

Secondly, I would like to know if it is possible to slow or speed up the time in the game, to create a "slow motion" effect.

 

Finally, I try to create a physic destruction, with a bullet and a wall : http://www.babylonjs-playground.com/#DBETC

 

The goal is to remove the physic link when the force is too strong.

To do this, I thought run a fonction test collisions with all objects, but is too long, due to the big number of meshes that compose my scene.

So, is it possible to call a callback function when the physic engine detect a collision ? If it is, how ?

And how can I remove a physic link between two meshes ?

 

Thank you !

You can create black particles by setting the alpha mode to standard:

 

myparticleSystem.blendMode = BABYLON.ParticleSystem.BLENDMODE_STANDARD;

 

Then you can change upadte speed for particles with myparticleSystem.updateSpeed

 

Latest point is not supported so far but I'm opened to contributions

Thank you, I understand now how use particle

 

And for the second point, I would like to slow every object in the scene, even the camera, all the world, not just particles, and without lost Frames. I don't think it is possible but I hope ^^

 

I will try to create my own function to remove physics links
