Making an "avoid the falling objects game", having array problems

lkvideorang

Hello, im trying to make a game where you keep a lit match from getting hit by water. The problem I am having now is that I want the drops of water to appear over time and not all at once. I have a drop class and a water class (this has an array of drop objects). Just curious as to how that might work, any general tips for anything you see are helpful! thanks!

 Idea: Have a user controlled match that when struck has a flame animation.
 If this flame gets close enough to a fire sprinkler then it activates sending
 water everywhere. While fire is going a song about heat is playing in background.
 colors flash and other stuff happening. Array for water effect, PImage and frames for
 flame. User input for location. Possible text in the background.

Here is the full file if you want it, it has the match images so the program can run. link

Chrisir

in the class Drops give them random values -200,-20 for y

in the constructor

thus they come out one after another

when one drop dies, assign it the same y random and a x random to restart it

line 78

Chrisir

for gamestate and key you can use switch()

also the 0 and 1 you could give names

final int gamestatePlay = 1;

make it all upper case since it's a constant

there are empty methods like move- delete them

try more comments in draw()

hit ctrl-t to auto-format

Thanks! I think I see what you're saying, looks good! The empty methods are filled in now, I just had not gotten to them yet. Ill update later if I can get everything working.

Chrisir

great!

;-)
