Air Hockey - Dark Theme
#1
For Danilin, vince and Pete Smile
Code: (Select All)
Option _Explicit
'Air Hockey v2-1.bas for QB64
' Started in QB64 Walter fork version (B+=MGA) 2017-09-05
' The first version was a direct translation from SmallBASIC,
' Now v2.0 add some more graphic image handling, try new things.
' 2020-03-11 v2-1 (QB64 v1.4 now) cleanup some code:
' Fix _MOUSEINPUT block too newbie ;)
' Fix flat spots on strikers how long have they been there?
' Increase frames per sec and slow puck speed for less double images.
' Oh that sped up the AI player! Nice.
' Do start shots to the side instead of directly at goal. MUCH BETTER!
' Update opening screen with this info. Now pause the puck at start.
' Ran OPTION _EXPLICIT and found a type-O that has been 0 all this time!

' v2020-03-23 Dark Theme as suggested by Danlin also fix fill circle with color
' also lighten color around the puck, oh fix the rest of the _rgb to rgb32.

WELL DONE!!!

Okay, so now everyone knows I tried it and at least beat the computer... or the response would have been something like: The game is buggy and unplayable. Still, it reminded me I may be old, but I'm still too good looking for AI apps like this, because I scored on myself way too many times!
