llSetTextureAnim

Summary

Function: llSetTextureAnim( integer mode, integer face, integer sizex, integer sizey, float start, float length, float rate );

0.0	Forced Delay
10.0	Energy

在指定的面上播放贴图动画（缩放，移动贴图）

• integer	mode	–	模式标志的掩码
• integer	face	–	face number or ALL_SIDES
• integer	sizex	–	水平帧数 (ignored for ROTATE and SCALE)
• integer	sizey	–	vertical frames (ignored for ROTATE and SCALE)
• float	start	–	开始的位置/帧的编号 (在 ROTATE 模式中是弧度)
• float	length	–	显示的帧数目 (在 ROTATE 模式中是弧度)
• float	rate	–	每秒的帧数 (不能为 0)

start supports negative indexes. If face is ALL_SIDES then the function works on all sides. 帧是按照从左到右，从上到下，从0开始的顺序来编号的。
如果 rate 是负数，和使用了 REVERSE 标志的效果是一样的。

Modes		Description
ANIM_ON	0x01	启用贴图动画。
LOOP	0x02	循环贴图动画。
REVERSE	0x04	反向播放动画。
PING_PONG	0x08	先播放动画，然后再倒放。
SMOOTH	0x10	在 X 轴方向上平滑移动，代替播放单独的帧。 在 SCALE 和 ROTATE 模式中，都会平滑移动。
ROTATE	0x20	旋转贴图动画， 不要和 SCALE 一起使用。
SCALE	0x40	缩放贴图动画， 不要和 ROTATE 一起使用。

Caveats

• If start is out of bounds the script continues to execute without an error message.
• The function silently fails if its face value indicates a face that does not exist.
• You can only have one texture animation on a prim
  • Calling llSetTextureAnim more than once on a prim will reset it.
• You cannot combine ROTATE and SCALE
• sizex & sizey are both limited to a range of 0 to 255

Examples

平滑移动一个贴图并且循环播放动画。

        llSetTextureAnim(ANIM_ON | SMOOTH | LOOP , ALL_SIDES, 1, 1, 1, 1, 1);

反向平滑移动一个贴图。

        llSetTextureAnim(ANIM_ON | SMOOTH | LOOP , ALL_SIDES, 1, 1, 1, 1, -1);

This divides a texture into 64 "cells", 8 across, and 8 down, and flips through them, left to right, top to bottom. This is useful for cell animation.

        llSetTextureAnim( ANIM_ON | LOOP, ALL_SIDES, 8, 8, 0, 64, 6.4 );

This rotates a texture counter-clockwise at 2 revolutions per second. Change the last value to -2*TWO_PI to rotate clockwise.

        llSetTextureAnim(ANIM_ON | SMOOTH | ROTATE | LOOP, ALL_SIDES,1,1,0, TWO_PI, 2*TWO_PI);

缩放一张贴图。

        llSetTextureAnim(ANIM_ON | SMOOTH | SCALE | PING_PONG | LOOP, ALL_SIDES, 1, 1, 1, 3, 2);
