NoGo - A Scriptable Game Framework - v1.5

[MinchinWeb]

A couple thoughts about trying to program a game script:

• - Game Scripts move really fast. Since they start immediately following map creation, by they time you get the debug screen up, they can have run several hundred lines of code.

• - Game Scripts keep running fast. They don't stop running when you push "pause" either. I might have to adapt Zuu's "break" signs...

• - I miss the libraries. I've been trying to move WmDOT over to run on the GameScript framework, but it depends on 5 or so libraries. I've managed to move most of the libraries to be internal files, but that's introduced some strange bugs (like the pathfinder always returns "null"...). Libraries support is at the top of my feature request list.

• - Bug: all GameScript options are changable in-game. I don't think this the intended behavior. (AI's can have settings you can set anytime or just before you start the game)

• - if a GameScript crashes, it does not pull up the debug screen with a message to submit a crash report, like it does if an AI crashes. Instead, the game continues to run.

I quite like the idea of Game Scripts, am amazed at what they can already do, and excited to see what can be developed.

Out of curiosity, what needs to happen before NoGo can be added to the trunk? Is the goal for it to be part of the 1.2 release?

@Zuu: I would be interested in helping with the tutorials. Do you have a basic curriculum drawn up yet?

[fieari]

If you don't have a curriculum set up yet, I have some recommendations for a tutorial. I only recently learned to play, using a guide, but I think this would be a good way to start:

Start with basic point-to-point RR between coal and power plant. This should be step by step (build stations, build tracks, build depot), and the two shouldn't be super far away.

Then teach RoRo, and add a second train (to a single lane station).

Then start teaching signals with a second lane in the station, maybe even adding another train to the line. Make it necessary by boosting production. Explain pre-signals! Perhaps cover another industry chain as well.

Then teach about transfers... do it with oil, so you can use oil tankers and trains combined, and teach how sea travel works. For added fun, make them build a canal.

Since oil leads to goods, next might be a good idea to teach about town growth. Also, get a local bus service up (make sure there's a big city in tutorial land).

Next, get forced transfers into play by shipping passengers via bus to an airport, which will take them to a distant city, and explain distance bonuses.

That covers trains, ships, roads, and planes, and gets the basic ideas across. In between these concepts, each of the industry chains should be covered as well, so that by the end of the tutorial, all vanilla industries have been serviced.

If you don't have a curriculum set up yet(...)

That sounds like a good route to go. Only thing I'd switch are setting up a bus transfer to an airport and getting a local bus service running. The latter is better to have setup first in order to make sure the town will continue to like you (serviced stations can improve your standing with towns)

Crash report... I trying to write a GameScript, and when I tried to exit the game, it gave me this message box and then crashed OpenTTD. I'm running 64-bit on Windows 7. I believe I have the newest version (h21d1ebea).

Coding help please!

I'm trying to write a Game Script, but I can't figure out why the following code doesn't work. It runs without errors, moves the viewport, but it doesn't do anything else. I'm expecting it to pay off most of the loan, then build a road section and a road depot.

I don't know if something in my code is failing or if something in OpenTTD isn't working the way it's supposed to... I'm running version h21d1ebea of OpenTTD-NoGo.

The code is question: (The full code is attached below)

Code: Select all

	local comp = GSCompanyMode(0);
	local exec = GSExecMode();
	GSLog.Info("Company " + GSCompany.ResolveCompanyID(0));
	GSCompany.SetLoanAmount(GSCompany.GetLoanInterval());
	GSLog.Info("Loan set to zero");

	local x = 50;
	local y = 40;
	GSViewport.ScrollTo(GSMap.GetTileIndex(x,y));
	GSRoad.BuildRoadDepot(GSMap.GetTileIndex(x,y), GSMap.GetTileIndex(x,y+1));
	GSRoad.BuildRoad(GSMap.GetTileIndex(x-1,y-1), GSMap.GetTileIndex(x-1,y));

GSCompanyMode is broken atm, and only works for the next statement. Will fix that with the next release

[Zuu]

Currently there exist a bug that GSCompanyMode is reset an the next DoCommand. In addition I've reported a bug to TrueBrain that I couldn't build a road bus stop as company 0.

If you don't have a curriculum set up yet, I have some recommendations for a tutorial. I only recently learned to play, using a guide, but I think this would be a good way to start:

Great! I haven't set up any plan for what the tutorial will contain. There is one in the wiki to use as inspiration but ideally this one doesn't need to follow it completely. The in-game tutorial should probably contain less text to read as reading a website is easier than reading text in the game, and we don't have to explain so much about where to click but rather use highlighting etc.

@Zuu: I would be interested in helping with the tutorials. Do you have a basic curriculum drawn up yet?

Great! I as said before, I haven't though so much yet about the text/tasks etc. in the tutorial. More on the architectural side. When the bug mentioned above is fixed, I will continue to work on the code and soon post a draft.

I think we should probably create a thread for this project. Will do that tonight I think.

[Eddi]

for a tutorial it could maybe be useful to highlight a TileArea.

• - Game Scripts move really fast. Since they start immediately following map creation, by they time you get the debug screen up, they can have run several hundred lines of code.

Add a Sleep() at the beginning of your script if you don't like this. Read one of my posts in this thread on the hows and whys

• - Game Scripts keep running fast. They don't stop running when you push "pause" either. I might have to adapt Zuu's "break" signs...

The way it was meant to be

(..)

• - Bug: all GameScript options are changable in-game. I don't think this the intended behavior. (AI's can have settings you can set anytime or just before you start the game)

GetSetting() system is identical to the one used by AIs. (they share identical code). So I need a bit more to go on than only this, if you think it really is a bug.
[Edit]Nevermind, finally found what you meant. But please do be bit more verbose with bug reports, my mind-reading machine is still broken Tnx

Should be solved with next update .. I hope. Let me know if it doesn't.

[TrueBrain]

Coding help please!

Besides the GSCompanyMode bug, there is one other mistake in your script. Like explained in one of my posts, the GameScript runs during map generation. In that time there is no company active yet. You should wait for the Company Create event before assuming there is one. In multiplayer for example this can be a while.

[Expresso]

I'm willing to help out with the tutorial, but it would be nice if GS can actually highlight user interface elements. That would spare a lot of explanation.

[TrueBrain]

Today I started to release based on versions, instead of Mercurial hashes. So, today I give you NoGo 0.1. The first of many I am sure

Fixes:

- GSCompanyMode is now fixed
- You can no longer configure a GS when it becomes active (read: start a game)
- Some minor GUI bugs
- Logging in GSCompanyMode no longer happens to the wrong window

Tnx all for reporting the issues. Hope you can now start building routes

[MinchinWeb]

I seem to have managed to crash it again... I'm running NoGo v0.1 this time.

If I were to guess, it's because I tried to do something as "Company 1", which doesn't exist.

Keep reporting bugs here?

lol, I don't think my mind reading machine works either...

• - Bug: all GameScript options are changable in-game. I don't think this the intended behavior. (AI's can have settings you can set anytime or just before you start the game)

GetSetting() system is identical to the one used by AIs. (they share identical code). So I need a bit more to go on than only this, if you think it really is a bug.

I was hoping for the option to change some options ingame; a GSCONFIG_INGAME flag to match the AI version. At the moment, using that flag cause the GameScript to fail to compile. Bug: I checked again, and it still seems like all setting can be configured once the same is started by using 'flags=0'.

Is it/will it be possible to build roads without making a player do it? I'm working on porting WmDOT, my AI which basically builds out the highway system, to the NoGo framework. If I have to go thru a company to build it, especially the player's company, I'm not sure I'm any further ahead. In order of preference, the options I wish were possible:

• 1. Build roads as the game (as town authorities?) That way they don't cost anyone any money, the bridges don't disappear when WmDOT goes bankrupt, and the roads can be removed by the player if they got in the way.

• 2. Start an AI, either WmDOT or a 'dumb' company directly run by the GameScirpt. This is about the same as the AI version...

• 3. Build stuff as the human player, and then have a way to "refund" him the cost of construction.

Are any of those three things (build roads as the game, start an AI, or give money to players) likely to be added to NoGo soon?

[TrueBrain]

(..) a GSCONFIG_INGAME flag (..)

http://devs.openttd.org/~truebrain/nogo ... 92bd834bd1

The flag is called: CONFIG_INGAME, like per documentation

PS: in the AI changelog is also mentioned that it is no longer AICONFIG_INGAME, but CONFIG_INGAME. In fact, for all settings the AI part is removed.

[ToxicSheep]

a little bit offtopic... does a anyone know the PW to xaroth.nl NoGo #2 server? I'm getting a 403 when I want to go on his site.

[TrueBrain]

Locally fixed the crash. Turns out that functions around Balance did not validate the validate-ness of a company. Nasty bug
Also locally fixed up the GUI to work with INGAME setting. It now used some kind of fifty-fifty system, it was funny
