Doubled gamespeed possible?

[Donnerkoettel]

Is there a known way of doubling the gamespeed? I know there is a funtion about that but i've read in this forum, that fastest is actualle normal speed. If it's only possible in jass, never mind. That would be to difficult for me to implement. I realy tried but at jass i am just terribil. I can barely implement custom scripts. -__-

I'm currently working on an idle clicker game, where this feature would be awesome. It will be singleplayer only.
