Question by Ekta-Mehta-D · Jul 28, 2014 at 05:19 AM · line point draw

Draw line from one point to another using mouse

Hello everyone..

I have scene like points will be generated randomly and i want to draw line in between those points.

So if i touch on any of the point i want to start that line and line should be drawn till i reach to the another point. Thats the way i want to draw line.

And if i could not be reached to another point then line should not be drawn.

Line should not overlap each other and new point also we can add by dragging line . How can i achieve this ??

Thanks to all for your help and support till now..

You bumped this, so I'm assu$$anonymous$$g you are still looking for an answer. Right now this question is too vague with multiple issues. You need to break your problem into individual issues:

How to display a line
How to connect points with a line
How to display the points
How to randomize the placement of the points
How to detect a near point to connect a line
How to avoid overlapping a line (can two segments share a point? Can a segment cross another line segment?)
How to select a line
How to drag a line

I'll give a bit of feedback on one aspect of your question: drawing lines. There are multiple ways of drawing a line, all with their strengths and weaknesses, and many are not very simple. Here is a partial list.

LineRenderer
Use real world objects line Quads or Cylinders
GL class
CustomLineRenderer
Vectrosity

The last one, Vectrosity, is a paid-for script in the Asset Store. You could draw all of your points and all of your lines in a single drawcall, and there is a bit of starter script that draws a line by clicking with the mouse.
