Angle between two points

Guardian

Hey Guys,

I'm new to GameSalad so don't slam me too badly

I'm trying to find the angle between two points and from what I've been reading vectorToAngle does just that.

"Usage: vectorToAngle(x,y)

Find the angle relative to the origin, (0,0), given an X and Y coordinate. You can include an offset,(x',y'), to find an angle relative to the offset.

e.g. vectorToAngle(x-x',y-y')"

So I did this to find the angel between the player and the mouse as shown below.

vectorToAngle(( game.Mouse.Position.X - self.Position.X ),( game.Mouse.Position.Y - self.Position.Y ))

However, I was expecting a value returned in degrees but instead I am getting negative values. What am I doing wrong? :S

it should be

vectorToAngle(self.position.x-mouse.position.x,self.position.y-mouse.position.y)

You don't need the extra brackets (but I dont think thats the problem) sometimes actors just get mixed up. Try this way around.

vectorToAngle( self.Position.X - game.Mouse.Position.X , self.Position.Y - game.Mouse.Position.Y )

ah great that's awesome. Good spot. Thank you.

However, I am still getting results between -180 to 180. How do I get results between 0 to 360?

Rob2

add 180

Well you see I thought that but I needed the angle to go clockwise so I did this.

abs(vectorToAngle( self.Position.X - game.Mouse.Position.X , self.Position.Y - game.Mouse.Position.Y )-180)

Now it all works

Thanks guys!
