How to save a rotation to position?

akichan22

i want to change an actor image depend on the position where he is going,
im using 2 different actor, one for record in a game.attribute the self.rotation to position X,Y.
I would like to use only an actor.
sorry for my bad english. thank you for help

Then don't rotate the actor.

To check the direction use the vectorToAngle expression and use that to change the image.

You don't need to record anything. Just make a rule, in your actor, that says when self.rotation is angle you want image to change. Change image to.

but i cant use the self rotation because if the actor change his rotation, the image too rotate.
mine is a monster that go to the hero, so i cant rotate it

how is your actor moving?
is it just a rotation position?

remember in coding it usually When then What
so drag in a Note behavior
type in it:
When: self X = ? ; Y = ?
What: change self image
now you see you have to create a rule:

Rule: when (All)
Attribute: self.Position.X ≥ (moving right; or ≤ if moving left) the X you want for change
Attribute: self.Position.Y ≥ (moving up; or ≤ if moving down) the Y you want for change
--changeAttribute: self.Image To: the image you want

The actor is moving to position HeroX,HeroY
I used like said FryingBaconStudios the rotation to position then the change image relative at the self position, i can modify the images but still don't know if possible to save the rotation in an attribute. ( i dont understand very well the attribute function, just few of those)

akichan22

ok i don't understand very well what vectortoangle do, but i check it

MotherHoose

to monitor the rotation …
drag a Display Text behavior into the rotatingActor
Text: Expression: self.Rotation … or floor(self.Rotation) for no decimals

on rotatingActor:
(lower the rotationSpeed so you see the Rotation place for your imageChange )

Rule: when
Attribute: self.Rotation ≤ number for change
--changeAttribute: self.image To: whatever

I used the VectorToAngle and it work perfectly, just saw the correct formula
vectorToAngle(x-x',y-y')
first then open this discussion i used it
vectorToAngle(x,y) whit Hero X,Y and obviously it doesn't work..

so thank you all

MotherHoose

a vector is a direction to/from a point … a line that intersects to points

in Rotation: Vector to Angle is the same as Rotate to Position

and moveTo can also get you the end points of that vector
