#

only when packaging?

turbid violet Jun 21, 2024, 12:49 PM

#

Yes

misty vigil Jun 21, 2024, 12:49 PM

#

can you show the class in question

#

at least the header

turbid violet Jun 21, 2024, 12:49 PM

#

#

misty vigil Jun 21, 2024, 12:49 PM

#

yeah i see a major issue

#

already

turbid violet Jun 21, 2024, 12:49 PM

#

these IF?

misty vigil Jun 21, 2024, 12:49 PM

#

#

this is at the top of the class

#

and i bet your header file still has the declerations

#

so it cant find anything to link again

turbid violet Jun 21, 2024, 12:50 PM

#

misty vigil Jun 21, 2024, 12:50 PM

#

scroll down more

#

why did you

#

if WITH_EDITOR the entire cpp file

turbid violet Jun 21, 2024, 12:51 PM

#

It's a plugin, not my code

misty vigil Jun 21, 2024, 12:51 PM

#

can you find BeginPlay in header

turbid violet Jun 21, 2024, 12:51 PM

#

misty vigil Jun 21, 2024, 12:52 PM

#

yup

#

thats the issue

#

remove the '

#

if WITH EDITOR

#

from the top of the cpp file

#

and the endif from the bottom of it

#

and give it another try

turbid violet Jun 21, 2024, 12:52 PM

#

ok, omg thank you so much, I will try now

misty vigil Jun 21, 2024, 12:55 PM

#

https://www.unrealengine.com/marketplace/en-US/product/snap-central this is the plugin right

Unreal Engine

Snap Central in Code Plugins - UE Marketplace

A plugin designed for runtime usage that provides a versatile and efficient solution for managing a precise 3D snapping system that spans across the entire world, ensuring high performance

#

is it any good?

turbid violet Jun 21, 2024, 12:56 PM

#

yeah, it works very nice

#

but it's only visuals and snapping

#

its very cheap for the functionality

#

you just need some kind of ''can place logic'' on your own on top of it for placing things for example

#

its well documented so you can see what it can do on the page

misty vigil Jun 21, 2024, 12:57 PM

#

yeah i made my own snapping system and building stability using subsystems and stuff

#

its similar to fortnites grid system

turbid violet Jun 21, 2024, 12:58 PM

#

you could consider putting it on marketplace, thse things are usefull

#

I tried to do my own for a couple of days and it worked, but I didn't know how to make materal visible on runtime by clicking key, so I got that and it worked out of the box, then I have my own grid on top of it which holds the logic. I need to rewrite it to C++ though because it takes so long to spawn whole grid (these are actors, terrible probably) xD

misty vigil Jun 21, 2024, 1:20 PM

#

any luck>

turbid violet Jun 21, 2024, 1:20 PM

#

misty vigil any luck>

The error dissapeared! I hoped to deliver information to you that everything is working but I'm now stuck on compligin shaders for 10minutes already xD

#

#

Thank you for the help with previous error 😄

misty vigil Jun 21, 2024, 1:21 PM

#

well you got past the compile bit

#

so any cook errors will be project related

turbid violet Jun 21, 2024, 1:21 PM

#

lovely 😄

#

if there is no error or success I should just wait?

#

because it's been like this for 10minutes at least

misty vigil Jun 21, 2024, 1:22 PM

#

let it finish cooking

turbid violet Jun 21, 2024, 1:22 PM

#

ok! 😄

misty vigil Jun 21, 2024, 1:22 PM

#

probably some big shaders

#

did you cook or package

turbid violet Jun 21, 2024, 1:23 PM

#

package

misty vigil Jun 21, 2024, 1:23 PM

#

i prefer to pacakge outside UE though

#

cause editor eats performance

turbid violet Jun 21, 2024, 1:23 PM

#

I did it here

misty vigil Jun 21, 2024, 1:23 PM

#

yeah

turbid violet Jun 21, 2024, 1:23 PM

#

you can package without editor? ill look it up

misty vigil Jun 21, 2024, 1:23 PM

#

yeah

#

thank you, ill read while this finished, btw it moved to the next line so there is progress 😄

turbid violet Jun 21, 2024, 4:31 PM

#

Well, if you were curious it's still going omg xd

#

I had some errors with structs on the way but these were yellow and probably blueprint was not compiled or something.
