Re:求助: 刀光剑影
实际上就是某种特殊处理的粒子，在物体运动轨迹上，一堆方块不断的高速移动。这些方块都是粒子。
暴雪的官方原文如下：
In the Warcraft III, many of the missile weapons and spells use a BlizRibbon helper. This object can be found under the
Create\Helper tabs. A ribbon is simply a line that dumps out a sheet of quads wherever it moves. If it never moves, it
can’t be seen, despite the fact that it is creating quads.
Above and Below ? These fields define the width of a ribbon in units based on their offset from
the origin.
Edges/Sec ? The number of quads generated.
Edge Life ? Time in seconds that the quads stay around after being generated.
Gravity ? Can be positive or negative. Will cause the ribbon to sink or rise in the z axis over
time.
Texture Rows and Cols ? Allows an animating texture similar to BlizParticle. Set the number of
rows and columns equal to the texture.
Texture Slot ? Pick the index number of rows and columns, and animate this number to get a
cycle.
Vertex Color ? An RGB multiple for the material.
Vertex Alpha ? A fixed alpha value for the material.
Material ? Use this to assign a Warcraft III material in the Material Editor to the Ribbon Object.
It pulls from the material the diffuse texture, blend mode, and many other texture properties.
