How do I a draw line between instances?

Hi all

Cant figure it out.

I have waypoints in my game (instances) and i want to draw a line between them going from first instance to last instance.

Any help is welcome!

Kind Regards.

Global vars for x and y, for each instance, draw a line from current to x and y, set x and y to current, next instance. Kinda like that.

The line would be a sprite you create at current position, rotate towards x and y vars and set length to distance between vars and current position.

I understand, but the problem is setting the angle and distance to the next instance.

I cant pick them?

Which is why you start with the next instance and then work your way back to the previously set x and y variables. Just add a check to start drawing from second variable onwards.

Thanx Somebody

Its working now.

I made a counter that ads up to the amount of waypoints (looping).

Using that counter i was able to pick the waypoints counting from 0 to the last.

Then i set the distance and angle of the line to the position (also stored in a variable) from the previous picked waypoint.

Now when i erase one waypoint all lines correct themselves automaticly to the new route.

Done with just 2 events & no variable. Just need to adjust image point for line sprite.

Thank u very much!

alextro - Wasn't aware of the Self.IID parameter, very elegant.

Proven that IID manipulation is rightious way to code

Nice alextro!
