Hi All,

Does anybody know how to create a saw blade that rotates using Gimp or photoshop or any other tool.

Thanks

    as far as the being able to rotate, you take care of that in game salad. you just need to draw a static piece of art. look at some pictures of a saw blade and just try and make something similar

    Something like this?

    I could write a quick tutorial on it - it's easy to do in inkscape or even gimp (though I would rather go with vectors ;) ]

    oh yes please, tutorial would be great, and in order to animate the saw rotating, do i change the rotation of the saw and save the image at each rotation?

    thanks mate

    You can blur the image for the rotation and just do two or three steps of rotation - to move the teeth enough to get to the next position. Put those onto of a blurred shaw shape and reduce the alpha a little. That way you should get a feeling of rotation.

    by adding another lighter alpha version of the blade it becomes even more obvious that it's moving.

    The level of detail will depend on the ingame size of the sawblade.

    I must ask since i'm not seeing why making the actual saw blade actor rotate would not be more desirable? it means only one image loaded into the ram instead of three? Is there a reason you would not just set a constant rotation to the actor?

    Good point, tenrdrmer... I was thinking from the artist point of view... You would just need one image or to make it a little nicer 2 - one for the still saw and one with blur for the rotation with the blur.

    to use the rotate behavior would mean making it movable. A couple of images might be better on fps if you have a lot of saw blades in a scene. Not sure what would be worse more images or more movable actors. just a thought

    @scitunes

    When self.rotation = 0
    -- interpolate self.rotation to 360

    No need for movable that will be a constant rotation. If you want it to go the other way just use -360

    oh yeah, good call. Forgot about using interpolate for that.

    Just had a play and using ease in and ease out gives it a really convincing look.

    Tap the square to saw and it will stop itself after a few seconds.
