Does spark work with Irrlicht 1.8?

Hey I figured it out, I was looking more closely at the example and after the node system is created it's dropped

Code:

system->drop();

so before this line is where any movement of any kind should be done so I move the node then call to update it's position and everything works fine. Thanks once more.

I'm having trouble attaching to a node.

Code:

core::vector3df Head_Position = node->getJointNode("bip01_head")->getAbsolutePosition();
node->getJointNode("bip01_head")->addChild(system);

No matter how I try to do these the system node will not link to any node??

I think it has to do with this line

scene::CSPKParticleSystemNode* system = new scene::CSPKParticleSystemNode(smgr->getRootSceneNode(), smgr);

Any suggestion?

1/ Glad you sorted your position problem !

2/ Normally it should reparent with add_child, but I'm not sure, at least you can set the parent when you create the system. I will investigate this.

Yeah you can set the system node position manually by passing the float's, but If you try to pass a node or joints position it seems to have no effect so you can't have the system node follow anything. I've even tried to parent the system to a dummy node and then pass all my transformations to the dummy node and not the system node itself and that had no effect either.

Hope you can find a fix. Other than that it's a great library lots of neat little features.

Hey noticed in spark 1.5 you can set a sprite sheet texture parameter to 0.0,4.0 meaning 4 individual sprites. But in spark 2 I don't see the method

Code:

****->setParam(PARAM_TEXTURE_INDEX,0.0f,4.0f);

. How do you set this in spark2?

Hey Darktib I got all my previous issues in the above post worked out ^^ just wondering if you found a fix for attaching to a node yet?

1/ Still not found the time the deeply investigate. That will probably wait this week-end.
2/ Texture index is "texture atlas" now, you set it the same way than the particles color (for example)

Glad you figured out your issues !

and for removing it to i'm having issues removing particle scene nodes from the scene


also an other issue is removing an emitter scene node without removing the whole particle scene node

Let me know if any of you guys fix the issue of assiging a parent node or a constant poition

I'm getting closer to the bugs, but to fix it faster I need:

1/ @The_Glitch: the code in which you create the CSPKIrrSceneNode (to be honest, post as much code as you can )
2/ @granyte: the code in which you create the nodes and the code in which you remove them (same comment as for The_Glitch).
Also, please note that as a workaround you can simply disable an emitter (the node is still here, but the emitter won't emit particles until you re-enable it).

Thanks !

Ill post code tomorrow

Sadly i cannot only disable the emiters as they are created and destroyed with the projectiles in my game.

I'll post mine. Mines mostly the spark Irrlicht examples. I'm using them to get a hang of spark library.

Heres a link to the main cpp so you see everything I do. It's a real small file.

Thanks for the code, is it possible to post the media files ? (especially the 3d model)

I can later not @ my pc. The model shouldnt change the results as my irrlicht node dont have the poisitioning issue.

Hey for faster results use the dwarf model that comes with irrlicht & try to attach the particle node to lets say his hand by passing the skin mesh get bone node and it shouldnt work and show the resulting issue.

Ok, will do for the moment.

Alright both models are .x format, so you should have the same outcome

singlularity array

Code:

       core::array<CSPKParticleSystemNode*> Singularity;

how they are created

Code:

SPK::Ref<SPK::System> sys = CreateGalaxy(parent->Enginefw);
       irr::scene::CSPKParticleSystemNode* BH =new irr::scene::CSPKParticleSystemNode(sys, parent, parent->getSceneManager(),false,ID_IsNotPickable);

   Singularity.push_back(toadd);

how they are destroyed

Code:

for (int i = 0; i < Singularity.size(); i++)
   {

      Singularity[i]->remove();
   Singularity[i]->drop();

   }
Singularity.clear()

ill post the code for the emitter objects later

Normally deleting a CSPKParticleSceneNode should remove the spark system AND the irrlicht node, meaning that you don't see it anymore after that.

However, CSPKObjectNode is a different beast, it is just a convenience node for manipulating SPARK objects, it does not create nor destroy them. So, deleting a CSPKObjectNode<Emitter> will not remove the emitter (just the Irrlicht node).
To fully remove an emitter, you should destroy any CSPKObjectNode associated with it, and then remove the emitter from any groups it is in (so the refcount mechanism will delete it).

@The_Glitch: Had little time to investigate the link to limb code.

But from my tests, it links correctly to the right parent (and the position is computed considering that). However, there was an offset between the parent and the system, I will see why. Tell me if that was your problem or not.

Well for me If I try to attach to lets say head bone node through skin mesh method. The particle node is way above he's head a big offset. But I also noticed while the character is animating in place the particle node doesn't move at all so I figured it wasn't working.

I will test it further (at least for the offset). Maybe the head bone was not moving ? I tried left and right hands of the dwarf.

Well let me ask this how are you attaching your particle node. In the stock spark example the particle node is system. So assuming that could you post yours maybe I'm doing something different.

I just used the code you posted, and changed the name of the 3d models and the name of the joint.

hmmm let me assign mine to his hand or foot. be right back
