How do I make an object slowly spiraling outward

I want do make an object move like the paladin hammer in Diablo 2. I've tryed to make the object distance itself from is origin point while rotating. (Rotation behavior). Thanks.

an object can not be distanced from it's own origin point.. try distancing it from any other point..

Well... it will have to rotate around is creation point, while getting away from is creation point. I can make a circle trajectory, but not a spiral.

Is creation point can appear anywhere at the location of the player.

Maybe the bullet behavior and the rotate behavior with negative acceleration?

An all event route could also look like this:

Global number dist=0

Global number ang=0

Every tick

--- add 100*dt to dist

--- add 180*dt to ang

--- Sprite: set position to (100,100)

--- Sprite: move dist pixels at angle ang

Is this what you need ?
