How can I implement pendulum physics in my game

I am making construct 2 game and I need a guidance on how to implement pendulum physics (not without physics). I want the user to drag and drop the ball (the ball has pole attached to one end) from certain height, let's say h' and when user drops the ball from h', the ball will swing just like real pendulum moves when dropped from certain height. How can I achieve this functionality. I have attached the link for the .capx file for the reference.

Any help would be highly appreciated.

Thanks for your time.

Hey msha91!

Here'a an example of one way of doing it. Click the ball to apply an impulse to it.

Hope this helps! Cheers!

brunopalermo Thanks for the example.

Your example is about impulse in physics, and I want to have a distance joint instead of revolute joint. I want to have a pole connected to a ball instead of creating a long chain that acts as a hinge.

I also want the user to drag a ball to specific height (let's say point A) and when the user drops over to the point A, it starts to move downward due to the gravity, a fundamental concept in physics, and then starts to and fro motion. I have attached the image so that you can understand what I am saying. Here is the link: https://drive.google.com/open?id=1uKZ_t ... zDkLs-R6ry

Nice demo, Bruno!

I added drag&drop:

It works, however the dragging distance and speed needs to be limited, otherwise the chain can break.

I wonder if it's possible to make an unbreakable chain?

I see that's not exactly what you wanted. Oh, well..

Cool improvement, dop2000!

I thought about adding drag-and-drop myself, but I had some trouble doing it and hadn't much time 'cause I'm at work, so I gave up...

Thanks for adding it!

dop2000,

Thanks for the improved demo!

I achieved what I was waiting for and also updated the post question, but a little problem. I have attached a 30 sec video in the link that addresses the problem clearly with text captions. Here is the link for the video: https://drive.google.com/open?id=14eL8- ... HACOTQ7a7i and for the .capx file: https://drive.google.com/open?id=10nmdc ... Vvj6R35RS0

But do you really need physics? If the "rope" is rigid and the object is not interacting with other physics objects, then this kind of movement can be done without physics behavior:

I really appreciate your effort dop2000,

Yes, I really need physics because I have to make the things like gravity acting on the ball when the user releases it and gradually slow down the to and fro motion over certain period of time.

I don't let the user to have the sine behaviour on the ball where the ball keeps the +ve and -ve cycle constant and does not slows down that cycle over time. This is unrealistic, not real especially when physics is involved.

I got a runtime error when I run the demo, for the first time only, (drop the ball to some height and again try to drag the ball while it is in motion) that you sent in the link: https://www.dropbox.com/s/yueo56ie8kxo0 ... .capx?dl=0

Oddly, I'm only getting this error in Chrome, in other browsers it works fine.

In event 8 move "Remove all physics joints" above the "Sprite set physics disabled".

This should fix it.

Thanks dop2000,

It works like a charm.
