Hi Guys How can I get an object to rotate around a point and get faster and when you stop touching the screen the object is launched in the certain direction it was facing in?

Heres a diagram:

The red ball swings around the black point and gets faster the longer you click on it and when you release your click it will release in the direction it was facing in when it was spinning, like a hammer throw.

That is brilliant thank you - how would I create the connector joining the ball and the point a chain? Also how would I change the speed depending on how long the player holds down for?

You have to set the origin like this

for hammer

for the point

for changing speed check subevent No3

The event No3 prevent speed to run more than 500, if you want you can change it.

Also at the action you add 150 to current speed , you can change also that.

You have to play with these numbers and the timer to fit your needs.

What I meant is how can I change it to 3 sprites origin, chain, and ball - how can I add chain like physics to this so its like a ball being swung round on some rope?

Ah, ok.

Sorry for the misunderstanding.

Well there is 2 intermediate examples 1) pin chain style 2) pin rope style

You can find it at start page when open the construct.

Hi, do you want the chain/rope sprite to look like an actual chain/rope with multiple parts and physics or can it be a straight line?

If you don't need Physics, this can be done with 2 lines of code:
