I use normal functions, all normal functions and delegation; and all works w/o any problem on V8, IE, etc (without surprises, nor limitations and also fast). I see that design can impose us limitations to "protect execution success" and can be not safe/possible to run my frameworks here. IMO the safety at expense of "each page/stage a world" is a severe limit for scripting a game. Is there a simple way to load js code when booting top context? (at root) I am asking for a place to patch the engine to load my file into javascript at boot... as it was part of core js impl. thanks for your time, Ale. p.d.: I am too old to stop when someone say "dont´do that". So if it is possible, I will try; if it is not possible (at js level), it is also ok; I can try to run in one page.
