Unity3D 刀光剑影特效：Trail Arc Renderer实现

Trail Arc Renderer unity3d中的刀光剑影特效
 


Description 
Alright, this is my last trail renderer I will post (wink). This trail renderer is designed specifically with melee trails in mind. It will track the path of its parent object and create a fluid arc between its saved points. You can set the distance between saved points, which gives you control over the accuracy of the interpolation. Increasing distance will produce more smoothed out arcs, where reducing distance will increase accuracy to the actual path. 

Features 
?Set the fade out time (lifetime) when the trail is done emitting 
?Control when its done by simply turning off the "emit" property 
?Set any number of colors 
?Set any number of widths 
?Autodestructs when faded out 
?Set the interpolation distance 
?Set whether it always faces the camera 
?Set the number of segments to place between each interpolation distance 

One-Time Use 

This trail renderer is designed to be a one-time use component. There are several reasons for this, based on the way it is designed for optimization. When emitting is set to false, the trail renderer will stop adding new segments and fade out. The fade out time is set to the lifetime.
