Game

Why does this not work?
What happens is, the main menu loads, then when I click
it starts but for some reason a different screen is loaded.
And the game doesnt seem to be functioning at all.
I know this is incomplete so no comments about that
What im not sure of is why the castle isnt being rendered
and why the cannon isnt and why the attackers arent there.

That link is interesting - when I click it it opens a copy of this thread.

I think the webspace provider doesn't allow directlinking, and if you try it neverless, it will redirect you to the referrer, that's where you came from, from here. Try to use the RMB - save as...

Zach: use the CODE tags for sourcecode: (code)...(/code), replace () by [].

Zach : it seems you mistyped "gamemode" in the function UpdateLevel(), should it be "Game_Mode" ?

Try eliminating the *(2/3) first line in the UpdateLevel() function

replace the line with:
MaxA = ((Level + 2)^2)

Since the expression is an integer (2/3) doesn't return 0.66 but returns zero instead
