Making a ray that follows the mouse

[ac3raven]

So, how would I go about making a line (ray) whose x1,y1 originates at a particular location, with the x2,y2 following the mouse (or following another object that also follows the mouse)?

I've seen it done before in an example file somewhere, but I can't seem to find it.

Depends...

You could...

Make a 1x1 pixel active called 'line' set the action point to be the bottom of it.

Use the Advanced Movement Object which allows you to calculate direction and distance between objects.

Then set the position of your 'line' to where you want it to start.
Tell it to always set the angle to the angle from the calculation.
Tell it to always set the scale X or Y (i think Y) to the distance between the 2 objects.


I think there is a line drawing extension, but if you just want a straight line, you can use the above method.
