How to display mesh(gun) instead of Collision particle ?

[chaiein]

I want to use a gun instead of a Particle.bmp in collision tutorials how can i do that? it should work similar to IBillboardSceneNode.

Now in the tutorial i am able to show a particle now i want to replace with a gun mesh how can I do that? Is there any command for mesh to behave like IBillboardSceneNode where i corresponds to camera.
Please let me know if I have to be still more clear in my question

You can try replacing the boxemitter with a meshemitter: http://irrlicht.sourceforge.net/docu/cl ... d5ee5a5161

[chaiein]

scene::IMesh* Meshgun=smgr->addMeshSceneNode("gun.md2");
scene::IParticleMeshEmitter* ParticleEmit=smgr->CreateMeshWriter
There is something wrong in above code please correct me. I want to use CreateMeshEmitter

[chaiein]

scene::IMesh* Meshgun=smgr->getMesh("gun.md2");
scene::IParticleMeshEmitter* PEm=createMeshEmitter(Meshgun, true,core::vector3df(0.0f,0.0f,0.0f),100.0f, -1,false,5,10,video::SColor(255,0,0,0),video::SColor(255,255,255,255),2000,4000,0);


Error 1 error C3861: 'createMeshEmitter': identifier not found

createMeshEmitter is a member-function of IParticleSystemSceneNode (same as createBoxEmitter).

Thank you cuteAlien now I got cleared the error but still in this following code

Code: Select all

if(receiver.IsKeyDown(irr::KEY_LBUTTON))
                     {
                                   scene::IMesh* Meshgun=smgr->getMesh("gun.md2");
                                   scene::IParticleSystemSceneNode* PEm=smgr->addParticleSystemSceneNode();
                                   PEm->createMeshEmitter(Meshgun,false,core::vector3df(0.0f,0.0f,10.f),100.0f, -1,false,5,10,video::SColor(0,255,0,0),video::SColor(255,255,0,0),2000,4000,0);
                                
                        }

I can't see the gun in the screen instead some square Thing is getting emmited very thick(many).


How to decrease paricles its size , change angle of emission and color. and make gun visible

I am getting particles moving upwards. and gun is not getting visible. how to change the direction of particle emission?

[CuteAlien]

Ok, sorry, I have misunderstood what that function does. I thought it allows to use meshes as particels, but I just read documentation and what it really does is export particle from the form of a mesh. So still normal particle, just the origin is different.

So I guess it's not possible to use meshes for particles, but it sounds like you don't want random guns flying around anyway. Can you maybe describe what it is you want to see exactly - maybe we can give another solution (like using an animator instead).

Thats ok no problem

Please help me in this
What I need is I have a weapon displayed , now it should emit a particle/bullet so when it reaches a another mesh or animated character(say a human) I should be able to destroy that human.

How does this emission of particle happen Even if i use this cylinder

Code: Select all

 
 
                                scene::IParticleSystemSceneNode* CEm=smgr->addParticleSystemSceneNode();
                                scene::IParticleEmitter* em=CEm->createCylinderEmitter( core::vector3df(0,0,0), 20, core::vector3df(0,1,0), 10, false,
      core::vector3df(0.0f,0.06f,0.0f),   // initial direction
      80,100,                             // emit rate
      video::SColor(255,255,255,255),       // darkest color
      video::SColor(255,255,255,255),       // brightest color
      800,2000,0,                         // min and max age, angle
      core::dimension2df(10.f,10.f),         // min size
      core::dimension2df(20.f,20.f));        // max size
 
 

There is no change from the previous createMeshEmitter. I am not understanding what's going on

We have a number of examples in the SDK which cover exactly this. Please go through the demo source code and find the solution.

[chaiein]

Sorry I did not find in the demo examples for my requirement. please send me link where i can find solution for my previous reply

[CuteAlien]

Uhm... just try shooting in the examples - I think it was the collision example - or maybe the demo itself (shooting is probably with space or left-key, not sure right now).

[chaiein]

Ya I got that demo Thank you:)
