C++ Tutorials - Absolute n00b spoonfeed

Well, after making some games in c++, as many others. I moved on!

I learned to do a little bit of allegro, lacking c++, but.. working on that part now!

Created a little game, that makes you able to move, shoot, destroy and win!

Well, not really sure if anyone here is into Allegro. But I thought, hey! Let's give it a shot! +)

Code: Select all

Well, of course... Because this is allegro.. It will NOT compile unless you include the allegro library, and the pictures I had been drawing myself (No, their not good looking :p lol)

So, the library is something you have to get yourself, and here is the link to the epic art!:

Well, could you get us files that are needed to run this (pictures as people who installed Allegro libraries got .dll files needed to run this program) ?

Thanks.

Thanks.

I'm going to try to get it for you, but rapidshare is being annoying today should be here soon

You can use megashare, megaupload...

their it is, specially for you! :p

OMG,dude you could use some imagesharing site,i have to wait some time for all those pictures :S Can you post only the .exe ? Thanks

http://rapidshare.de/files/48414837/FUL ... M.zip.html

the full thing compiled :O


hope u dont mind if you do il give you the kill link <3

AAAARRGH! it says it can run because alleg42.dll was not found. lol

Look here

Copy the .dlls out of the allegro bin folder and paste them in the same folder that has the .exe
