ok, i have simpley 2 keyframes… and all i want is a basic preloader where the bar expands horizontally… 1 keyframe is the preloader, 2nd keyframe is the content… heres my code stop(); loaderInt = setInterval (Lbar,10) function Lbar (){ if(getBytesLoaded()\>= getBytesTotal()){ play(); clearInterval(loaderInt); } fill\_MC.\_xscale = (getBytesLoaded()/getBytesTotal()\*100); } now when i preview, the loader just pops up, no loading, and theres a few errors… i am following a tutorial… what am i doing wrong !!! _here are the errors_ 1180: Call to a possibly undefined method getBytesLoaded. 1180: Call to a possibly undefined method getBytesTotal. 1120: Access of undefined property loaderInt. 1180: Call to a possibly undefined method getBytesLoaded. 1180: Call to a possibly undefined method getBytesTotal. 1120: Access of undefined property loaderInt. ty kirupians
