What the parts are worth
Posted: Thu Sep 18, 2008 12:57 pm
Found while looking for Tulip's patch.
The four part items (And several other tiles like the pogo) have the possibility of giving Keen something else besides the spaceship parts, anything from ammunition to a pogo to allowing him to skip levels.
At the same time, what is marked as having 'got' a part can be changed too; you can get a highscore entry for finishing level 16 for example instead of having got the whiskey. This is controlled as follows:
EDIT: Added a bit more detail
So for example, setting the Joystick to $A8 means that when it is got, level 2 is automatically done and Keen can skip it. (But the joystick is not given!) Setting it to $CA $AA $64 makes it a 100 point item. You can make parts give you several keycards, or take a pogo or even make it so a level is 'undone' and can be played again.
I have also added patches to let you change the conditions, so you can win if you have x or more of something instead of the default win ONLY with x.
I hope this fires up people's creativity :)
