Engine will stop spawning start units and resources

[Tobi]

You could spawn the start unit directly in LuaRules' main.lua

[FLOZi]

but you are making it more complicated on mods that don't want random starting units...

Not really as the gadget is provided in the base files to be backwards compatible, you just have to have gadgets set up..

If I did not want any lua gadgets in my mod, would my mod run in any capacity?

Would basically never happen.

[zwzsg]

The exemple 'game_spawn.lua' provided doesn't work:

Code: Select all

Unsafe attempt to change game state

Not sure if it's best to fix by allowing unsafe changes or by moving the spawning to GameFrame.

[TradeMark]

cant you leave the default behaviour if some file is not found etc?

will just make mods harder to make when the amount of needed lua files is growing constantly.

[Argh]

It involves dropping exactly one file into LuaRules. It's not the end of the world.

[TradeMark]

yeah.... and what next, one another lua file... then one another... and so on.

[SinbadEV]

yeah.... and what next, one another lua file... then one another... and so on.

NO, it would involve adding a few lines of code to said one file until all of the behavior required to make a TA game with the spring engine has been moved out of the engine proper and into a single lua file and we can finally get the open source community to like us.

[TradeMark]

okay... few lines of code vs few files is as messed up IMO.

[SanadaUjiosan]

I don't know, I'm happy with leaving the engine in the hands of those who are capable. If we want Spring to get better, it'll have to change. Just the way things work.

[TradeMark]

well... theres no cons in making default options really

[ScarySquirrel]

Wow, even more improvements.
This is what makes Open Source great: it's always improving.

[zwzsg]

Here is a better version of game_spawn.lua

• Switch off error about unsafe change
• Snap start unit to 16x16 grid
• Start unit face toward map center

[hoijui]

zwzsg, i have it ready to put into spring source, put i do not get the snap-to-grid thing. i mean... i can imagine what id does, but what is it good for? could it be negative for any mod?

edit: .. is it that in-game, you can only place buildings into this grid too?

[zwzsg]

For mods that start with mobile units, it doesn't really matter since the unit can move.

A naive concern would be that displacing units could make them spawn in a cliff or acid if they were already very close to it. However, a proper examination dispels this argument: if you stay within the same 16x16 cell, you are in the same passability "tile" gameplaywise.

For mods that start with immobile units (Gundam, EvoRTS, KP, ...), it makes them align to the building grid that all the regularly built structures are forced into. This helps with two things:
- Decals alignement. For start pos that are not roundish, decal gets slightly misaligned. It's a hard to notice small detail, but would still looks a bit sloppy.
- Lining up with regulary built structure around the start structure.

edit: .. is it that in-game, you can only place buildings into this grid too?

Is it an actual question I'm supposed to answer?

Link in first post should be updated to reflect new git directory structure

[Tobi]

Thanks, updated.

[bobthedinosaur]

I'm sorry, I am confused. Where are devs defining what units are the start units with this gadget?

[zwzsg]

Spring.GetSideData fetches it from your mod /gamedata/sidedata.tdf
