How to make bullet follow the line just drew

Yes, please help me about how to make the bullet follow the line ?

Hold down left button mouse and move the mouse to draw a line, when finished, the bullet will follow the line, but i don't know how to do it, someones help me.

Here the capx:

bullet_follow_line

Hmm, it could do with some finess, but here's a capx

I made a few quick changes, some instance variables etc.

It marks the first dash and spawns the rocket there, it also deletes previous dashes once the rocket has exploded.

I think there's still a bug with lerping angles, as lerping the angle to make smoother curves causes it to spin wildly as it only works in a positive direction it seems.

JohnnySix ,@farsmile90 , if you see the capx i can drew a line and when i stop click with the mouse and move my mouse another place and click it will create the line, i remember when i post about this creating line and i really didn't like the idea because of this lol i think the link should be created on array it will be easier :)

about my capx here is it maybe you wanna use it

Thank you JohnnySix and zsangerous, i'll see what i can do with your great help. When i finshed , i'll post the capx in here, sry for bad Eng.

good luck XD i wish you can fix it :)

wow, it's hard to make a bullet travel smooth with high speed :( any idea people ?

You could test for the difference between angles of the line and the rocket being positive or negative, then have a sub event that interpolates in a positive or negative fashion.

I did try smoothing it with LERP(Dash.Angle,Rocket.Bullet.AngleOfMotion,5)

but lerp will only turn clockwise, so you'd need to filter into two sub events and test if the difference is positive or negative I think.

That would smooth out the turning. :)

Here is a way to make the rocket follow the path:

The dashes have a variable to indicate which rocket uses it so each rocket will follow it's own path.

Omg, Thank again JohnnySix and great thank to R0J0hound for your awesome help here. Work perfect.

If i done somethings with it in my game i will thank for you in credit.

sry for bad Eng .

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?

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

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)

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

ramones, where had Ashley said he'd reverse those changes? I thought it was clear that he wasn't going to.
