zig zag motion

bhaktaraj

Hi all,
I have a missile I and want that to travel in zig zag motion. please help

Wingmanapps

On your missile actor
put in a timer
every 4 sec
change self.rotation to 45

create new rule
If self.rotation is = 45
Put in a timer
after 2 sec
Change attribute self.rotation to -45

But there are many ways to do it.

CodeMonkey

Reduced code:

Change self.rotation to 45 (unless it already starts at 45.
Timer: Every 2 seconds change self.rotation to -self.rotation

Perhaps a more organic, 'fishy swimmy' type of zig-sag movement is wanted:

Constrain Attribute: self.rotation To: (angleToTarget)+(30*cos(self.Time *500))

@rthurman you sexy beast - you always have such refined solutions. Love it =D>

@Wingmanapps ) Wow, didn't expect that!

RThurman

I am afraid @Socks gets all the sexy credit. I stole the formula from his signature.

(I guess I'm nothing but a cheap and tawdry imitation. Still -- it's nice to stand offstage and see how the rock stars of GameSalad work their magic.)

@RTurman @Socks is indeed a master of GameSalad. I've used that same formula many a time in my games.

hi @RThurman‌, i was wondering what you meant by "angleToTarget", did u mean "vector to angle"? My missile is moving from right to left of the screen. am using the move rule and the above constrain attribute that u suggested, but still going nowhere with it. Can u show me where am going wrong with it. Thank You

RThurman

@djdee‌ -- wow! blast from the past!

Yes, 'angleToTarget' would be an attribute that contains the angle from the hero to the target. It could be calculated by using 'vectorToAngle' or perhaps some other way.

RThurman

@djdee‌ -- here is a quick example

djdee

thanks a lot @RThurman‌

RThurman

@djdee‌ -- you are welcome!

And ensure your direction of movement is set to actor not scene! maybe!
