Hi!

I have next problem…

So I have this case

And I want to have 2 cursors starting from the same point with the SAME SPEED.
Obviously, they have different road (circle is shorter) so they should split right away and circle should finish his cycle first.
But I have problem setting it up in IanniX. There are 2 options – ‘Cursor length’ – which is not helpful, because I would have to count the road of both curves and ‘cursor speed’ which seems for me the good one. BUT – setting both of them on 1.0 (which for me is logic – ‘1’ should mean same speed) makes something weird. The circle cursor goes afterwards far more slowly than the other one…

So… How make 2 cursors go with the same velocity?

Hi!

Speed of “1” means 1 grid unit per second. If you type 2, it’ll be 2 grid unit per second.
Because the shapes are different, the perimeter of the curves are different so you may want to set a fixed duration, which is the order field right next to the speed field in the inspector!

So I have to count the perimeter for both shapes and than set the time? I wanted to evade this one…:(

No no, just use the duration instead of the speed!

But I have to set duration for both of them in the way, that cursors would go with the same speed. That means, that durations of 2 curves are not equal. They vary because of different perimeters… So to count, using the simplest equation v=s/t I still have to know the “s”. Am I wrong?

In IanniX, you can enter the speed OR the duration. It means that if you want that the cursors finished their run on the 2 curves at the same time, you have to set the duration.
If you want them to have the same speed, you have to set the speed.
