No way to remove default resources in the editor.

[Angelo Locritani]

It seems that there's no way to force zero resources on a tile, because if you don't add resources inside the editor default applies.
For example, in greenland worlds, defining no fishes for water tiles let the default of 4 fishes apply.
The same for water.

Linking a branch that add possibility to see current resources of a tile in debug window

[Astuur (wolfsteinmetz)]

You're right it seems - what I thought might work didn't.
Can't set any water tiles to 0 fish.

This has a merge proposal attached which was merged a year ago. Is this fixed and released in build18?

(And if so, can we retroactively tie it to an already released milestone somehow? That would be the most correct approach probably.)

[SirVer (sirver)]

The merge proposal did not change anything here, so this is still confirmed and important.

Setting to incomplete for bug sweeping.

I just played with this a bit and I can not see what is this about. Resources amount as reported by field->get_resources_amount() can be set to zero, and DBG window for a field (in game) confirms this.

[wl-zocker (wl-zocker)]

I just tested it in r7261. Place a lake in the editor, put no fish in there. Start a game on the map, build a fisher -> he finds fish. I have no debug build available, but there is fish in the lake.

[TiborB (tiborb95)]

I think that when somebody creates map he/she adds fishes manually and default values does not matter much.

[SirVer (sirver)]

I agree that it must be possible for a map maker to explicitly set the number of resources on a field to zero - i.e. no fish in a lake.

[kaputtnik (franku)]

Can some one explain what the default_resource_amount is good for at alll? From my understanding they are "just there" but nothing else depends on it (yet).

[GunChleoc (gunchleoc)]

I guess the original idea was to save map editors some time?

If we remove it, it might break some old maps - that might be taken care of by map loading compatibility code though.

[kaputtnik (franku)]

Yes, better show them in the info tool, as first step. So a map maker has at least the possibility to examine the default amount.

Removing could be implemented if we have overlays for resources: https://bugs.launchpad.net/widelands/+bug/778540

[kaputtnik (franku)]

Another idea:

1. Remove default amounts
2. Add a check to the editor which checks for some things and if the check fails, open a window showing what is missing.

E.g.: 'The map does not contain any fish/water/coal/gold/players/..'

The check can be executed automatically on map save, or with a new button 'Check playability' (maybe in the Save map dialogue).

[hessenfarmer (stephan-lutz)]

In the empire 4 scenario I had the same problem. I solved it by removing the ressources via lua script.

My preferred solution would be:
1. Having a button "apply default ressources" for each category in the editor to save some work
2. Apply them for older maps in game as now using some compat code

[GunChleoc (gunchleoc)]

The applying for older maps is non-trivial, because we don't have versioning for maps on the website yet.
