Auto Credit Based on SnoWFLakE0s's Functional Semi-Automatic Rifle
Credit to SnoWFLakE0s for his blow back action. We have also been working on a bottom fed mag, but still not reliable. This one works most of the time:)
- AG1 to cock it, then release AG1 to load the round.
- And then just FireGuns.
- If there is a jam, then AG1 on/off to un-jam it.
- AG2 for full auto!

Its probably the distance between the gun and bomb... try moving backwards and forwards... also, you can try just saving the gun on this as subassembly ams just use it...

@SpirutusRaptor
how did you get the projectiles to actually shoot? i see you’ve used wing guns, and i’m trying something similar, but i have no idea how you got the boom 25s to fire. the wing gun’s bullet just seems to go through it. is it something in the XML? any help would be appreciated
When you skip the tutorial
It looks like a top fed thompson
Please let me see any prototypes you have when you are ready...
@ChisP
Some points on the below:
- Having casing is difficult as the 'bullets' are not attached to anything and we don't use in-game firing system so that means there is no way to detach the casing when firing.
- We're trying to avoid using Activation groups for each round as that will limit the number of rounds.
- The piston and spring idea is good, but then there will need to be some work on timing etc... see the drum type mag on the link below.
- Yes, there is a balance to achieve between impact force and the main spring to get the right speed... for the current uploads we have gone for a relative slow movement due to the explosiveness of the rounds. The paint ball guns are faster.
@ChisP
This is the drum mag... just hit fire weapons, its still prototype/development. ie. not ready.

@ChisP
But if you want to send me the prototype drum mag then I might be able to make something more suited for that
On the spring though what will have to happen is that you have a small spring and a piston and the spring is in contact with the bullets and then an activation group to extend the piston increasing the pressure but the mag might have to be half full cause there will have to be room for the spring
So I tested something and with the piston in the fire system you can set that to fire guns and the piston will do a better job at actually sliding the bolt back setting an amount would be the hardest part. This then fixed the issue of the bolt not sliding back all the way so if I’m able to recreate a spring with a piston and shock we would be able to push the bullets up faster creating a faster rate of fire as well. But instead of the piston I could also try to increase the impact force so that it’ll slide the slide back further but also increase that tension so it comes back faster. I think that solution works better though cause then you can still have that piston and it keeps a realistic chamber.
For that ejector you could use a piston or you could try to have the incoming bullet push it out although idk what you would use for an ejector
You could also make flat laying casings as well and you can turn off aircraft collisions so the casing don’t fly with the bullet and have something that ejects it as well so you have basically a working gun@SpiritusRaptor
I can see but I’ll have to get home and on the computer might take a couple days I’ll use your mag on the Thompson as a base@SpiritusRaptor
Do you have a mock up for the bottom feb mag idea I could see?
@ChisP
Firstly, the reason for the weight was if you are moving the fun and firing at the same time... also with the elevation above 10 or 15 degrees the bullets start going wonky in the mag.
@ChisP
SR I took off the “ weight” attached to the winches and found that you don’t need it. It actually runs much more smoothly without it and has less jams/misfires and the bullets fall into the chamber more naturally.Hopefully, you can use this to create other popular top fed guns such as the Bren gun or the boys AT rifle both used during ww2. Another suggestion for any bottom fed /curved mags is to create a string of springs connected to floppy rotators creating a spring like effect.
@Supernovaboss504 I've also attempted as well.
@SpiritusRaptor I might try again after this project, what do you think?
That would have been frustration I reckon!
@Supernovaboss504
We could try - there are the standard Boom25 and 50 guns on planes... very cool to shoot stuff with them @Randomdoggo
@SpiritusRaptor a long time ago I Tried to make a belt fed gun
@Randomdoggo Read the preexisting thread, if possible. Under development, and to put it on a plane would be difficult to make the mechanism smaller.
@SpiritusRaptor I thank you for actually accepting ideas from a noob like me because a lot of people let their fame go to their head but not you so thanks
Its down to timing... i e tried, and any slight deviation from the timing and kaboom - I have a drum mag that is times to dire rate vs. rotation speed with nothing really to upset the action ans that works mostly
@Supernovaboss504
@SpiritusRaptor what if you had pistons activated by the landing gear and have it the length of the mag and have it set so that when you are foreign full auto every time a round is fired another is pushed up by the piston(s)
