Football lift with gravity

**salaam** · 04 December 2008, 06:35 PM

I don't know if you know about this feature in XX Flash.

To give a realistic lift and fall to objects moving in one direction, apply a [rotation] to the [name].
This animation's football is called [rotation-ball]. Therefore it has a negative rotation applied to it causing it to lift gradually. The ball start positions are all the same (O°). The 5 different examples show a variation of angles attributed to the end position balls. The bigger the angle the greater the lift.
The O° start to finish [tween] (example 1) rolls along the grass, (as the rotation centre is at the centre of the ball). The following examples do not roll as much because by giving them angles, the centre is moved down (below the animation). The start and end football positions are all the same on the 'y' axis.

Nows that's Cool Anas. Can you post the .xar also?

Very informative Salaam

Thanks for sharing!
But it doesn't look like a football to me

Thanks, here is the .xar file as requested:

The most important frames are the 5 'k' and the 'e' frames. They state the ball start and end positions.
The image shows the angle indicator box. This box moves around the centre of the object when you alter the angle using the [rotation handles] or typing in the [angle of selection].

Aridzone, I think you are getting it confused with a rugby ball.

This one is for Aridzone, Rugby not Football.

Nice one Anas

Thanks Egg.

Here is another sample of this method with the .XAR file to look at.

And a present:

I must confess, I don't quite understand how you get the ball to rotate

How about a short tutorial

How about a short tutorial

A [named] object (rotate+dot) is placed on the top of dotted circle line.
This frame is [copied] and this second dot is moved to the bottom of the circle.
The second dot is then rotated 180 degrees (about it's centre).
This last frame is then also copied.
This third dot is moved to the start position and rotated another 180 degrees (making a full circle of a total of 360 degrees).

I hope this makes sense.
