Attaching multiple lines to separate shapes

Gragnit

Good afternoon to everyone. I trust you're all well on the forum. I was wondering if any of you would be able to help. I would like to have multiple lines attached to each one of my 6 object, the beginning of line would begin at the top of the screen. So when the user clicks on the object it moves, but the lines are still attached to the centre of the object. It makes the lines look like they're being stretched. I've managed to create a set of lines for the first object, however I'm having difficulty creating the next 5. Would any of you be able to help with my problem please. Thanks all.

line 87

why addy as x-value?

isn't that the important line or which one?

Gragnit

Hi Chrisir.

Thanks for the quick reply.

The addy was there just to separate the lines along the top of the window, so they aren't generated on top of one another. The second point for all the lines are attached to the core of the shape MyCoor[counter].x, MyCoor[counter].y.

My problem is duplicating the whole set and then moving the first point of the lines along, to the top of the window and then the second point being attached to the core of the next shapes.

Chrisir

no need for ; after }

you need to put the sound again

I made the white lines now

;-)
