底图尺寸吗?
CCProgram fs %{
precision highp float;
#include

in vec4 v_color;
#define iResolution vec2(195., 270.)
#if USE_TEXTURE
in vec2 v_uv0;

};
void main () {
// vec4 o = vec4(1, 1, 1, 1);
vec2 uv = v_uv0;
vec2 p = vec2(.5, .5);
vec2 off = p - uv;
off.x *= iResolution.x / iResolution.y;
float dis = length(off);
float r = .02;
r += u_time * .6;
float width = .005;
float border = .01;
border *= r * 30.5;
float circle = smoothstep(r + width + border, r + width, dis) - smoothstep(r, r - border, dis);
uv = uv + (uv - p) * circle;
vec4 tex = texture2D(texture, uv);
circle *= .2;
circle *= max(.1 - dis, 0.);
gl_FragColor = vec4(tex.xyz, tex.w);
}
}%

怎么样在ts里面动态改变圆心的位置呀 大佬
论坛搜索 setProperty
mark 冲击波
加上*(dis-r)* 2.有奇效
为啥我搞出来的效果很奇怪 圆会一直扩散
好家伙666666
打开页面学习,后面同事以为我搞黄色。
不邀请你同事一起嘛?? 好东西要分享啊
可否参考一下?
