Realistically could any bugs pass through this wall of turrets I made?

[subtle anvil]

When I first played the game, I spawned in a desert and I was attacked by bugs within 1-2 hours of playing. I ended up restarting my save file and this time I never saw a single bug. I'm 8 hours in and the bugs still haven't noticed my steam production and started attacking. I'm really nervous that once they do attack me, it's going to be in insanely large numbers. So I made this wall of turrets that auto-reload piercing rounds. Would this be enough to get me through the next 10 hours or so? I'm about 8 hours into this save file. I didn't make it past the 5 hour mark on my first save file so I have no idea what to expect in terms of bug attacks.

[warped cipher]

it might, depending on how much you pollute
I would recommend using flamethrowers though
or at least putting the walls in front of the turrets so the biters attack those before destroying turrets

[subtle anvil]

Okay I'll do that then. I haven't unlocked flame throwers yet as I've hit a road block in my technology tree production. I either have to find Oil or start adding military science packs to my lab setup. Both tasks seem daunting atm 😭

Thanks for the info!

[runic latch]

military science is a huge buff to gun turret damage
what you have is quite excessive for your stage of the game, but amusing

[dull musk]

Military science packs arent too bad finding oil might be the more daunting task depending on its location

[subtle anvil]

I'll definitely work on military packs next then!

[runic latch]

the gun damage bonuses are applied twice to gun turrets, multiplicatively
so the damage actually gets to be quite strong - which helps a lot against the biters getting flat resistance as they tier up

[subtle anvil]

they tier up??? oh god

[subtle anvil]

but yeah okay that sounds really useful, I'll prioritize that for sure

[runic latch]

you can alt+click one and see their stats

[dull musk]

Yep they evolve i believe with time the more u kill and pollution i believe

[subtle anvil]

good to know, I'll do that once I actually see one 😅

[runic latch]

can also alt+click the ground and navigate over to the enemies tab

[subtle anvil]

horrifyingly cool

[subtle anvil]

ohh shit

[subtle anvil]

do you know what menu is supposed to pop up when I alt click the ground? I'm trying to find the keybind in the controls page. I'm on Mac and it's not working with any of the system keys Mac has (control, option or command)

factoriopedia

i'm assuming you're unable to alt+R/alt+G/alt+C for red/green/copper wire then?

[warped cipher]

the exact name and location

[subtle anvil]

I haven't done anything with copper wires yet so idk for sure

[subtle anvil]

thank you, found it

• Place turrets behind the wall. You want the wall to take the damage, not the turrets.
• With enough physical damage and fire rate upgrades it will probably handle most end-game attack waves with some turret losses.
• Flamethrower turrets are a lot better at killing biters. Consider covering the wall with them as well. Fuel with crude or light oil, your choice. They only use fuel when attacking, are supplied by pipe and sip fuel when attacking.
• You want roboports to keep the wall repaired. This is how the walls will sustain indefinitely without player attention.

[subtle anvil]

Will the turrets target and shoot the bugs through the wall? If so, will the wall take damage?

[hallow goblet]

yes, no.
just test it, worst case reload before you did the thing

[runic latch]

annoyingly, spitter projectiles go over walls too

[subtle anvil]

will they try to attack my stuff with the projectiles???

[runic latch]

mostly the turrets

you can set target priority if you want to change what they shoot at

by default they shoot the closest enemy

later when i get laser turrets, i like to have them focus spitters

[subtle anvil]

ohhh interesting, okay yeah i'll def prioritize the spitters. I've started getting bugs now but my turrets take them out so fast I never can get a look at them. so I'm not even sure if spitters have started spawning yet

[tight mural]

Yes they will shoot biters through the wall. No the wall will not take damage from their shots, they shoot over the wall. Be aware spitters also shoot over the wall.

[subtle anvil]

how do I know which things are at what height? Is there anyway to tell? I didn't even know that turrets can shoot over walls

that's super helpful to know

[tight mural]

Flamethrowers will also shoot over the wall, but their fire damage can damage vulnerable entities of yours where it lands. Walls are not vulnerable to fire but something like transport belt and pipes are.
Rocket turrets will also shoot over walls, but if using explosive rockets or atomic bombs the splash damage will hurt your stuff.
Rail Guns DO NOT SHOOT OVER WALLS. They will destroy the wall and absolutely everything in the path of the projectile.

[tight mural]

There are no heights. For the gun and laser turrets there are no collision checks performed as they are instant hit, similar to assault rifle and pistol.

Factorio does support projectile collisions, your shotgun will work as expected and walls will absorb and be damaged by the shots. Just for missiles and the like they do not collide with stuff.
