用Python程序自动生成Blender Animation_Nodes 粒子发散动画01

用如下代码可以自动在Blender中生成AnimationNodes动画。视频效果如下

。

    bpy.ops.mesh.primitive_monkey_add(location=(0,4,10))
    msource = bpy.context.object

    if len(mssource.particle_systems) == 0:
        bpy.context.view_layer.objects.active = mssource
        mssource.modifiers.new("part", type='PARTICLE_SYSTEM')
        part = mssource.particle_systems[0]
        
        settings = part.settings
        settings.count=200
        settings.frame_end=120
        settings.lifetime=100
        settings.effector_weights.gravity=0
    
    bpy.data.node_groups.new("NodeTree","an_AnimationNodeTree")
    bpy.data.node_groups['NodeTree'].name='MyNodeTree'
    ng = bpy.data.node_groups['MyNodeTree']    
    
    particleSystemsFromObject = ng.nodes.new("an_ParticleSystemsFromObjectNode")
    particleSystemsFromObject.location=(-600,0)
    particleSystemsFromObject.inputs[0].object=mssource
    
    
    particleSystemParticlesData = ng.nodes.new("an_ParticleSystemParticlesDataNode")
    particleSystemParticlesData.location=(-400,0)
