How To: Draw Lines Between Two Moving Active Objec

[drnebula]

I need to draw a line between two active objects that will both be moving. Could someone give me some advice on how this might be accomplished. For example, which extension would be the best to use? Thanks in advance.

You can use the Active Overlay Surface Object for this. http://www.fusionwiki.com/wiki/Surface_object

I think the way it works is you select "Draw Line" in the event editor (so likely you'll use an Always if you want it to always update- else you can just trigger it once with a button) set the start point as X= XActive 1 Y= YActive 1 and the end point as X= XActive 2 Y= YActive 2, then set the colour of the line and the width.

I'm a bit new to the surface object myself so I don't know the exact way to do it.

Ok the correct way to do it with surface:

1. Create a Surface object from the Extentions List
2. Create 2 Active Objects (Active, and Active1)
3. Set their Hotspot to center on both
4. Go to the Event Editor
5. Create an "Always" event
6. On the part of the grid under Surface left click to bring up the menu for that extention
7. Select "With Color" option
8. Select Draw Line
9. X1 = X(Active) Y1 = Y(Active), X2 = X(Active1) Y2 = Y(Active1), RGB 255,0,0 (Red), Thickness = 1
10. Create an event which makes one of the actives move, on that same event, make surface do a clear by selecting "With Colour" "Clear" and select the colour 0,0,0 (Transparent).
11. (optional) if you want to stop the flicker when it clears copy the draw line event into the same cell and make it draw directly after the clear, this will then update as the object moves in real time with no delays.

There you go that should then produce a red line between the two that updates when they move.
