PVelocity

PVelocity

This node enables you to set the velocity of particles. Velocity is a vector; it incorporates the speed (which is the length of the vector) as well as the direction (alignment of the vector). So, using this node, you can set both the speed of particles as well as the direction in which they are travelling.

这个节点使您能够设置粒子的速度。速度是一个矢量，它包括速度(矢量的长度)和方向(矢量的对齐方式)。所以，利用这个节点，你可以设置粒子的速度以及它们运动的方向。

This node takes priority over other nodes that affect velocity. In other words, no other node will be able to change the velocity of the particles while the particles are connected to a PVelocity node.

该节点优先于其他影响速度的节点。换句话说，当粒子连接到 PVelocity 节点时，没有其他节点能够改变粒子的速度。
