pro13以后的版本使用的代码:
calc(local.xframes, (caller.imagewidth /framewidth) BOR 0);
calc(local.frames, xframes * ((caller.imageheight / frameheight) BOR 0));
def(local.frame, integer, 0);
calc(caller.crop, '0|0|' + framewidth + '|' + frameheight);
setinterval(calc('crop_anim_' + caller.name), calc(1.0 / framerate),
if(caller.loaded,
inc(frame);
if(frame GE frames, if(caller.onlastframe !== null, callwith(caller, onlastframe() ) ); set(frame,0); );
mod(xpos, frame, xframes);
div(ypos, frame, xframes);
Math.floor(ypos);
mul(xpos, framewidth);
mul(ypos, frameheight);
calc(caller.crop, xpos + '|' + ypos + '|' + framewidth + '|' + frameheight);
,
clearinterval(calc('crop_anim_' + caller.name));
);
);
calc(local.xframes, (caller.imagewidth /framewidth) BOR 0);
calc(local.frames, xframes * ((caller.imageheight / frameheight) BOR 0));
def(local.frame, integer, 0);
calc(caller.crop, '0|0|' + framewidth + '|' + frameheight);
setinterval(calc('crop_anim_' + caller.name), calc(1.0 / framerate),
if(caller.loaded,
inc(frame);

mod(xpos, frame, xframes);
div(ypos, frame, xframes);
Math.floor(ypos);
mul(xpos, framewidth);
mul(ypos, frameheight);
calc(caller.crop, xpos + '|' + ypos + '|' + framewidth + '|' + frameheight);

url中是png序列图片的路径,要使用正确。
