liaocheng iS it possible to have the particles follow an object and be affected by that objects movement? (leaves a trail)
eg
smoke from car tyres
torch in a characters hand

not just particle copy position of object.

Liao, thanks for assisting!

However, I am sorry to say that my IDE can’t find some classes. I am using FDT, set up a project using your src/ folder AND example/ folder as sources. I am also referencing src/ of minimalcomps and broomstick as referenced project.

However, when I, for example, search my file system for VelocityAction.as, it cannot be found.

Is that a dependency from somewhere else?

Thanks again!

Now it’s not possible.The movement of all particles has been determined previously.So we can play it backward,while we can’t change the movemoent dynamically.
Mybe we can add a action that dynamically pass on some param to influence the movement.Maybe this can implement the trail.I’ll do some experiment.Thank you!Cheers!

Hey,the VelocityAction is replace by VelocityLocal.Mybe your example is old
version but src is later version.

Sorry.I forgot update the Template.as.Mybe you complie it will occur these errors.

Yea also some examples like the snow need(ed) to be updated.

the ColorVelocity effect is so cool!:)

good job liaocheng, thanks

I’m glad to say that I have finished the trail.Please refer to the trail example on git.

Just had a little play
Ooh that so good
Thankyou

Found an issue.
If the camera doesn’t have the origin in view. The trail disapears

In the trail demo
add
_view.camera.lookAt(object.position)

to the render loop to see what I mean.

This is because the particleContainer is out of the view (the particleContainer’s real position is (0,0,0)).At render stage,the away core first call isInFrustum to judge if the object is in the scene.if not,the object will not be passed to render.Maybe I can provide a interface to set the isInFrustum always return true.

From a quick test/random guess.

Putting this in ParticlesNode stops it disapearing

override public function isInFrustum(camera : Camera3D) : Boolean
{
if (_particlesContainer.visible == false) return false;

_particlesContainer.pushModelViewProjection(camera);
return true
}

Yes,it is.I have added a interface to set it.

Hello,

Great work!
I’ve get started easily thanks to your exemples and came with this. (I’ve done a function to random a point in a random triangle for a given subGeometry, if someone is interested, I’d be happy to share the code.)
By cloning the container I was able to have 1.250.000 particles (at 55-58 fps in FP Projector)!

I had a look at some ParticleActions code and tried to figure out how I could apply the BrokenLineLocal “sequences system” (ie. having multiple vectors with duration) to ColorTransforms (ChangeColorByLifeGlobal is not PerParticule, and there is only two ColorTransforms, and no time). Any idea which option I should follow?
Also, is it possible to ease the movement/color progresses (like with functions as SineOut, QuadInOut, ...)?

Cheers!
