Where was that enemy radius detection example?

TouchTiltGames

I think Tshirtbooth had it up somewhere, it was to demo - if an actor or bullet was close to an enemy radius it would react to it....Anyone know where that is?

The distance between two points is called 'magnitude'. I have a magnitude demo on my wall that you can look through.

magnitude is used like this:

myMagnitude = magnitude(Actor1.X - Actor2.X , Actor1.Y - Actor2.Y)

Rule
When myMagnitude < [some number]
-----[do something]

Hey FMG, Thanks a lot yeah I saw your demo it's cool but a little to complex for me at this point lol. This is what I have:

On the Actor:

When game.bombClose = 1

Change attribute: game.bombClose to: magnitude( game.bombRadiusX - self.Position.X , game.bombRadiusY - self.Position.Y )

When game.bombClose > 100
Play Sound

On the Bomb:

When game.bombClose = 1
game.bombRadiusX to: self.positionx
game.bombRadiusY to: self.positionY

Doesn't seem to be working for me

In the above example what does game.bombRadiusX represent?
Do you have game.bombRadiusX constrained to the x position of something?

TouchTiltGames

Oh ok, On the bomb I constrained

game.bombRadiusX to: self.positionx
game.bombRadiusY to: self.positionY

Still isn't working hmm..good thing I bought Photics GS book
