Nvisionxr_ios Tutorial Eight--adding particles to the scene

This section describes how to add particle effects to your scene. Open the code for the previous section
1. Add header file #import ' NVWorldParticles.h ' 
2. Drag the particle's resource file into the userres.bundle directory(The resources in this section are available below the tutorial) 
 

3. About making particle files, this is not a narrative, please see the tutorial "nvisionxr engine Basic introduction http://www.arvrschool.com/read-7381"  )

4. Click Particle file, view the material name, and thenuserres.materialto configure the material path, such as:
 

in theonCreatemethod to instantiate a particle in a session, such as:
 
Code: 

Nvworldparticles *snow = (nvworldparticles *) [[Self Getworld] getobjectbyname:@ "Snow"];         if (!snow) {snow = (nvworldparticles *) [[self Getworld] createobject:particles objectname:@ "Snow"];         Set the particle script name [Snow settechnique:@ "Snow"];     Set particle coordinates in space [snow setposition:nvposition (0.0, 20.0, 0.0)]; }

in theOnstratmethod to attach particles to the scene, such as
 
Code:

Nvworldparticles *snow = (nvworldparticles *) [[Self Getworld] getobjectbyname:@ "Snow"];         if (snow) {[Snow attachto:self];     The particle system starts playing [snow start]; }

in theOnStopmethod to remove particles from the scene, such as
 
Code: 

Nvworldparticles *snow = (nvworldparticles *) [[Self Getworld] getobjectbyname:@ "Snow"];         if (snow) {//Control particle system end [snow stop];     [Snow Dettach]; }

To run the project, you can see such effects as:

The particle effect is added successfully, and you can try to use the particle editor to do a cool particle effect loading into the scene.
