increasing difficulty

RocketBrain

hey all, need some help.

in the timer behavior can the time be a value such as game.difficulty?

the game i'm working on needs that time to be reduced gradually so i tried doing

timer: every game.difficulty second
spawn actor: actor1

timer: every game.difficulty second
change attribute: game.difficulty = game.difficulty - 1

in my mind that should make game.difficulty go down by 1 second every round, and then spawn an actor that many seconds.

so set the starting value at 10.

first round every 10 seconds it spawns actor one.
next round every 9 seconds..
next round every 8 seconds..
....

but it doesnt work. any ideas?

hmmm should i be using a rule?

Make the spawn timer (10,9,8...) also a variable that dynamically reduces by 1.
Use a game counter that ticks up with each spawn that counts how many actors are spawned.
Then in an invisible controller actor...have a rule that states:

[ DEFAULTS ON SCENE START ]
change attribute: game.gameOver = false
change attribute: game.roundID = 1
change attribute: game.spawnCount = 0

RULE:
when game.spawnCount = self.spawnsPerRound and game.gameOver = false
.....game.roundID = game.roundID + 1
.....game.spawnCount = 0 (this resets the counter for the next round)
.....RULE (EMBEDDED IN ABOVE RULE):
..........when game.roundID = 11
..........game.gameOver = true (this will shut off the loop when 10 rounds are complete)

Then have in your game's controller actor as well...below (and separate from) the above rule:
RULE: when game.gameOver = false
...Timer: every [ 10 - game.roundID ] seconds >>
.......spawn actor >> actor1
(this will spawn an actor from 10 to 1 seconds with a reduction by 1 second each round)

Then in your separate spawning actor...
RULE:
game.spawnCount = game.spawnCount + 1

Another way to do your spawn timer is:
Timer: every [ 2 - (game.roundID * 0.1) ] seconds >>>
.....spawn actor >> actor 1
This will make the actors spawn every 2 seconds at first round...then reduce by 0.1 seconds to 1 second by the end of the 10th round.

The key to working out logic sequences like this is to take everything 1 tiny step at a time making sure each step is executed flawlessly before programming the next step. Don't try to do things simultaneously...do things in a sequence.

thanks bud, that really helped.
