Allegro help needed.
Posted: Thu Jul 22, 2010 8:38 am
Hi. I am new in Allegro. I know basics of C++. Took a few tutorials of that.
As for allegro, i cannot find any 'advanced' tutorials. Only tutorials for beginners, working on how to detect collision, how draw a picture, insert a sound or an animation.
Is there any websites, which are not so popular on Google, i haven't found, with little advanced tutorials? I am creating my first Allegro game which is Ping Pong. I got the idea, as someone has given an advice to someone else at other forums, to create ping pong as a first game. I currently would like to create a specific speed for a ball and the paddles. Also i am failing a detecting the collision on the paddles. The ball is not reacting to the paddles and just keep bouncing on the screen's walls. I have used this tutorial to make the ball moving by the way:
Any help is greatly appreciated. I would love to learn these things. But please explain what you write, so i can understand everything clearly.
P.S. generally, for the tutorials, i am looking into creating just a few simple basic games, not a Mario like game. To keep things simple and learn efficiently. Later i would like to move to those Mario style games. But that would be after i would work on a few such style games, to get the methods of creating basic and average stuff good.
Thank you, if you will help me learn Allegro.
