I tried loading a swf through

<mx:SWFLoader source="game.swf" /> 

(The game.swf is a flash free game if this helps) But it displayed blank, white screen. Why?

Flash is a historical aspect of the web , something that some of us used before web 2.0 . Flash is not supported anymore in any major browser (some give you still the option to download it an other just having weird messages like Chrome). So don't use Flash . I am not aware of the “<mx:SWFLoader” tag , I am aware of the mx namespace but it isn't a tag and shouldn't work in any case.
