it may be enough to save only the position of the last placed entity + tick and compare it with the entity position that is mined next
not sure if this will give the correct result always, got to try

having a hashtable that saves every entity built that can be replaced, is extremely bloated way to do such a small thing

That does not do what i would like it to do.

it is about xp gain from placing entities, but if you fast replace it goes bonkers, so it needs to ignore replacing of entities

don't understand how that would help

Right now, it seems that it throws entity built and mined event.
Is there a way to determine when a player manually replaces/upgrades an entity, like a transport-belt?

A sprite drawn with a file path like "file/picture.png", disappears after saving and reloading the game. For example: rendering.draw_sprite({sprite = "file/picture.png", target = {0,0}, surface = game.surfaces.nauvis, orientation = 0, x_scale = 1, y_scale = 1, render_layer = &quo...

Would be great if there was an option to toggle this on and off.
Or have some kind of slider for the intensity of the flashing effect, or some different ways of noticing character damage.

My eyes don't like it >.<

Yes, removing seems good. Performance gain is very good! Fluid simulation is something so complex, surely it can get a cpu hog very quickly. And the temperature is not even really much used in vanilla is it? Modders can still always make different fluids and just call them hot, molten or cold if the...

Does someone know good ways to increase the health of all biters scaling with time in a scenario?

It could even be with resistance or some other workaround.

It has to be done without creating new unit prototypes.

Players are using LuaSurface.spill_item_stack in some scenarios to spill items on a conveyor belt intentionally.

Can we still have the option so it spills like that. Maybe some boolean value? Else this old mechanic would be broken.

Made a scenario which has an anarchy / battle royal flair with optional team alliance creation. Every player starts as their own force initally and can opt to create a team and others can join them. Now i only now discovered you can only have 64 forces maximum. Since games with a few hundred players...

The health values on some tanks are very low.

A vanilla pipe piece has 100 health.

The big 7000L tank only has 100 health too.

500 is quite huge, can be a hazzle too sometimes if they are set too high.
But for plates it is neat and only makes sense because the rest of the plates are all set to 500 stacks.

Can we have it so that iron and copper plates stack to 500, just like lead / tin and other plates do?

Yes,
you can do that with the on_built_entity event and a global variable that saves the amount of already built structures.
If there are too many, you can destroy it and reinsert it into the players inventory.
Maybe even print a message so they know that the limit is reached.

Writing a map that generates a battle arena and places players into it. After the round has ended, the surface of the arena will be deleted and a new round will begin.

Yes, please!

The save file is too big maybe to attach it, hope this link is fine enough?

The performance drain from flame turrets happens in other maps too.

The Flamethrower turret is a big performance hog. Maybe too many damage calculations? Maybe too many flames? I am creating custom maps for the community and wish the flamethrower turrets would not put the game in a slow motion mode when they fire up. The issue arrises usually in later game stages. W...
