[mobichan]

An example of making an object swing like a pendulum using sin/cos.

It stops too suddenly, that is unrealistic, it should slow down then accelerate in the other direction and move back, otherwise excellent job.

Note: You can use Sin/Cos to do this.

He used sin/cos... I haven't got the chance to look at it, but It sounds good if you used sin/cos correctly!

I just noticed something with this. The object gets placed in an absolute position before it starts as seen here.
Set X Position to 320+(Sin((AngleTo( "Active" ))-90)*Distance( "Active" ))

How about adding 2 more alt. values (Value D, Value E) named Pos X and Pos Y. Use 'Start of frame': Set Pos X(Value D) to X("Active"), and Set Pos Y(Value E) to Y("Active"). Then in the always event, use this instead.
Set X Position to Pos X( "Active" )+(Sin((AngleTo( "Active" ))-90)*Distance( "Active" ))
This way, the swinging object is not always bound to a specific position on the screen before swinging. It would have its own starting position.

I know this is something a little bit extra, and probably not necessary for this example, but it helps.

Check my reply in the same topic mobichan is reffering to, to see how you can do the yposition with sine too.
