Thinking about it some more, i guess, the real issue is that time wasn't properly calculated.
Its based on the position of the target and not on where you want your bomb to drop.
Time between these two positions can be quite substantial so thats why you see such a big effect.

So to properly fix it you probably have to calculate time differently. My solution was a mere patch job so to speak.

Lol nvm my earlier question. I did not know what i was talking about.
After some coding and testing, i have found the solution to your problem!

The issue was with:

Code:: local velocitychange = VMult(displacement, 1/time)

Due to time changing, this value also changes. But that is ofcourse not what you want. You want the same displacement each time.
So you only need to calculate this value once for each line. And then reuse it for later bombs.

Hope thats what you wanted.

I put my changes into the spoiler tag.

Spoiler: show

I just thought about just giving you the file. So i'll add that aswell.

Don't the napalm lines just folow the direction the bombs are going?

I guess you should let the dispersion of the bombs on each line be along the original direction and not along your adjusted direction?

PS: looks nice. And liked your efficiency

This could be the result of the bombs being fired rather then dropped. Now as the bombs that are created are launched in the direction of the weapons "bone" (part of the unit model) they apear to be thrown / ejected from the bomber rather then simply falling to the ground. Hence why they are spread out but remain roughly parallel. The problem will be known once i'm able to read the unit blueprint /script as well as any other modifications he's made. Also be aware that dropped bombs assume the forward momentum of the bomber dropping them. The spread is caused by motion along another vector in combination with the bombers flight motion. (both motion vectors are added together)

Now if i had made this script I'd of opt'd to edit the unit script instead of the blueprint. Thus i'd have the bomber drop extra bombs and offset their initial position and velocity to have more control over the effect.

Off hand I'd look at the projectiles release speed. Too fast of a projectile means that its being tossed away from the bomber instead of dropped. Ideal drop speed should be 0 to 2 but never randomized as this would lead to uneven bomb runs.

Can you link a pastebin as the Githhub link isnt working for me.

multiple bomb drop code shenanigans

2016-09-17T19:48:55+02:00

ok soooooooo some IceCreamer asked me to make bombers drop multiple runs of bombs at once. cool. i did it.

the code is even configurable from the unit blueprint so no messy script editing if its not needed

however as you can see in the second picture, the bomb runs spread out. this means my code isnt working properly (

i would like to have some help with working out why this is the case. i suspect its something to do with sideways acceleration on the projectile somewhere but i dont know where that comes from, either that or my physics is failing me now (
https://github.com/FAForever/fa/pull/1513
you can view the code here, all for the glory of equilibrium of course.

i thought it might be useful to post this so that if and when this is fixed it should be flexible enough to use for a variety of bombing run weapons and whatnot. enjoy.
