i am creating a game similar to this.

[maxdelphi]

Hello, thank you very much for your answers, because I'm learning to create games, took many months to Unity 3D, and I know more than the basics, indeed, I was able to interact with the "Mouse", the question was, what formulas mathematics used to launch objects?, plain and simple, oh another thing, I do not want to copy the game, just a personal project because I liked it "Penumbra Black Plague. "

thanks.!

and sorry for my expression, but, my primary language is Spanish.....!
