Constraint of Rotations?

[pastrana]

I want to create a puzzle with several square images and:
-Constraint image rotation (via mouseups) to 90, 180, 270 then get back to 0 (4 movements)
-get the number according to the rotation grade (is the picture at 180º?) and send that value to a variable so I can compare it with other pictures
-if the values I want are true then execute (an animation, etc..)

I already got the rotations to work but I can't find in the documentation how I can constraint them until it gets to 270º

any help?
(attached drawing with concept)

thanks!

One approach to some of your requirements might be to put the following in the script of your images:

Code: Select all

on mouseUp
   rotate image id (the id of me) by -90
   put the currentRotation of me into myRotation
   if myRotation is empty then
      set the currentRotation of me to 1
      pass mouseUp
   end if
   put myRotation + 1 into myRotation
   if myRotation > 3 then
      put 0 into myRotation
   end if
   set the currentRotation of me to myRotation
   put myRotation
end mouseUp

This rotates the image 90 degrees clockwise with each mouseUp. The orientation is stored as a custom property of the image, currentRotation, which can take 0,1,2,3 as its values. The very first time you click the image, the currentRotation of the image is empty- the image is rotated 90 and the currentRotation set to 1. The final “put myRotation” is just to see how things work.
