rotation?

eboy

I have asked this question before, but i am just not getting it to work, i am new to the gamesalad way....so I would like to have a wave that moves up and down in a random way with a little forward and backward motion. i cant seem to figure out the best way to do it...would u use a rule or how could u set up the rotation....if someone could help me out I could get to the next level. Thanks...

Maybe if you could draw it out?

How do you mean 'up and down in a random way with a little forward and backward motion'?

hi, i just want an actor graphic to move up an down with a wave like motion. I haven't been able to figure it out, do you use a timer? how would I get the motion to go up a bit and then down a bit and loop and a little random and maybe add a little rotation clockwise and then counterclockwise. thanks for any help.

Rotation can be separate from up and down motion.
Timer: Every 1 seconds: Change Attribute: self.RandomRotate = random(0,1)
Rule: When Attribute: self.RandomRotate = 0
--Rotate: Clockwise
Otherwise:
--Rotate: Counterclockwise.

Up and Down Wave Motion:
Change Attribute: self.InitialY = self.Position.Y
Constrain Attribute: self.Position.Y = 100*sin(self.Time*200)+self.InitialY

how do i make a regular actor rotate by itself like a windmill? (im not controlling the actor)

Just put a rotate behaviour in? No other behaviours needed...

eboy

you da man. thank you.

eboy

what is the difference between

self.InitialY and self.Position.Y

where do you find initial Y?

I really wish you guys would do a few more GS tutorials on the basics of GS, the wiki is sorta limited, in my newbie opinion.

self.InitialY is a custom attribute you make so you have a starting reference point.
