I thought it might help if I gave you a capx of what I've done:

http://dl.dropbox.com/u/73268676/controller.capx

youll see i have changed the rocket to 2 monsters for now, and made them bigger so i can click them easier for the test, slowed it down too


if you click on a monster instance and draw a path the monster starts flying off all over the place, i tried setting the dist_to_next back to 0 on the mouse click which helps but still similar results


basically what im after is you should be able to click on a monster and draw its path, it will follow it BUT if you click on it again while its on that path and draw a new path, the original path should be dtestroyed and it should move to the new path

I played about with looping the dashes where the rocket variable was the instance you cclicked on and destroying them but then it doesnt move at all, maybe i was destroying the first one straight after it was created, i dunno, I'm really stuck]]> Thu, 20 Sep 2012 10:14:18 +0000 http://www.scirra.com/forum/how-to-make-bullet-follow-the-line-just-drew_topic53718.html http://www.scirra.com/forum/how-to-make-bullet-follow-the-line-just-drew_topic53718_post355728.html#355728 Author: theames

@Ramones you are a GENIUS!!!

I have one more favour to as of you and I will leave you in peace I promise!

I'm really struggling with this which is why I am asking, but I would like to amend your capx so that I have multiple instances of the rocket already on the layout, and I would like them to have a speed set from the start, so they are all moving slowly in a direction when the game starts. I then want to be able to click on a rocket and then draw the path for that rocket

Problems i have are setting an initial speed causes the rocket to just jump down the page vertically while i am drawing the line

another problem is when i mouse up after drawing the line, i am then able to drag and drop more lines which get joined on to that one.

I set this up by simply setting an initial speed on the rocket and changing the line where you spawn an instance of the rocket, i changed it to detect the mouse click over an instance of the rocket

Any help super appreciated and I will definately be adding you to the credits with massive praise when this is done]]> Thu, 20 Sep 2012 09:47:15 +0000 http://www.scirra.com/forum/how-to-make-bullet-follow-the-line-just-drew_topic53718.html http://www.scirra.com/forum/how-to-make-bullet-follow-the-line-just-drew_topic53718_post355684.html#355684 Author: adagar

@Ramones, where had Ashley said he'd reverse those changes? I thought it was clear that he wasn't going to.]]> Wed, 19 Sep 2012 20:46:00 +0000 http://www.scirra.com/forum/how-to-make-bullet-follow-the-line-just-drew_topic53718.html http://www.scirra.com/forum/how-to-make-bullet-follow-the-line-just-drew_topic53718_post355620.html#355620 Author: theames

Thanks for getting back to me this has drive me mad all day so it's good to know cheers

I started using way points plotting them down by keeping checks on the distance the mouse had moved but it was very inconsistent. Got no idea why. But this one you have sen me seems to do the job so cool and thanks again]]> Wed, 19 Sep 2012 20:09:23 +0000 http://www.scirra.com/forum/how-to-make-bullet-follow-the-line-just-drew_topic53718.html http://www.scirra.com/forum/how-to-make-bullet-follow-the-line-just-drew_topic53718_post355586.html#355586 Author: ramones

@theames Recent changes to how objects are spawned have broken it but Ashley has suggested that he'll reverse those changes so it may work again in r104. Here's an updated version anyway that works around the spawning issue.
rocketFollowPath_fixed.capx (r103.2)

Also line segments seem to get drawn ahead of the mouse point so it seems like the condition of the distance being greater than 20 doesn't work properly. I would really appreciate anyone helping me get this to work properly]]> Wed, 19 Sep 2012 14:39:15 +0000 http://www.scirra.com/forum/how-to-make-bullet-follow-the-line-just-drew_topic53718.html http://www.scirra.com/forum/how-to-make-bullet-follow-the-line-just-drew_topic53718_post355533.html#355533 Author: theames

@R0J0hound I get a lot of problems with your capx, the line you draw seems to create additional segments coming off it so the rocket shoots along the line then keeps going off then back to the main line, know what i mean?]]> Wed, 19 Sep 2012 13:17:53 +0000 http://www.scirra.com/forum/how-to-make-bullet-follow-the-line-just-drew_topic53718.html
