More player choice comes to missions in Alpha 11

A long ago requested feature from mapmakers and player is to have a choice in missions. It is coming to Knights Province Alpha 11. With this new feature missions can ask player in a convenient way to make some choice. No more “enable this house repair to get A and train a scout to get B”.

Let’s explore the details. This is how the typical script for the interactive messages going to look like:

procedure OnMissionStart;
Actions.PlayerMessageWithButtons(-1, 'MessageWithButtons prompting player to choose an option', ['Option 1', 'Option 2'], [1,2], True);

procedure OnScriptButtonClick(aPlayer: Integer; aTag: Integer);
Actions.PlayerMessageOpen(-1, 'Player ' + IntToStr(aPlayer) + ' has chosen button #' + IntToStr(aTag) + ' how cool is that!');

The script above has 2 main parts: message instantiation and click event handler. Instantiated message looks like so, with up to 8 buttons for now:

When a button gets clicked, the message closes itself and sends an event to the script.
In our example we just show another message with the event arguments, but mapmaker can write any other script (give wares, destroy houses, spam enemies, reveal fog of war, proclaim victory or defeat and much more):

And now to some technical details for mapmakers – click event has to be separate from the message instantiation (aka asynchronous) because of several reasons:

  • Dynamic script occurs within the main game update loop, which is separate from UI loop. This means that script can request a message to be shown, but the message can be shown (and processed) only after the game tick is done.
  • All player input has to go through recording mechanism (which is required for replays) and that mechanism basically works as <game update> <player input> <game update> <player input> … Since button clicks are player input, then need to go into the next tick.
  • Messages can be blocking (modal) or non-blocking. With non-blocking messages player can click the buttons at any time later in the game (or do not click any of them at all).
  • Since messages do not get deleted, player can click the same button over and over again. Emitting the click event again and again.
  • Last, but not least – given multiplayer architecture, player input needs to be sent to all other players and acknowledged before it can be executed. This can take up to several dozens of ticks

Finally, this is just a prototype. If all goes well, choice and interactivity can become much more sophisticated. Dialogs, other kinds of controls (text inputs, checkboxes, etc.), controls in the overlay area, etc.

Fish count display

Some time ago I was reworking fishing mechanics. Biggest flaw that had to be fixed – unnatural fish depletion. Now fish slowly regenerates. To make it work, waterbodies had to be made to keep track of their fish reserves. One additional benefit is that building a dozen of fishermans houses would not increase overall catch amount, but only affect speed at which fish gets caught.

Having this mechanics for a while, made me realize that I’m not entirely happy with it, but can not put a finger on what exactly feels wrong. From game mechanics point of view, it works as it should – providing good starting nutrition source that is slowly depleting, but never too much to cause Fishermans houses demolition to be a good move. Mechanic itself is a bit less clear, fish count increments are a bit vague, but still on par with old approach. UI display – that’s what requires the most attention and work!

Current display (numbers on terrain) was totally unnatural for the games visual style and has to be reworked. But how? The idea is to mix a heatmap with a fluid. Let it be a bit vague and flow-like.

These are work-in-progress shots. First attempts at visualizing fishcount with a very blurred texture sharply cut at certain value and filled uniformly red. Done in special preview-tool dedicated to water effects:

Checking that all the tiles align well between texture and the terrain:

Two separate layers, to indicate higher fish density:

First in-game shot:

Tweaking transparency and density:

Fish can not be caught anywhere nut the shoreline, so it makes sense to show the effect only there. Also trying out different scale – looks interestin, but too noisy. The water should be calm:

Applying Fog of War effect

Trying out fishcount effect without blur – looks good for a Minecraft clone:

Again more tweaking:

Forgot to disable texture tiling:

This is how the final effect looks:

Been working on hotkeys for the last week:

The system is hierarchical – there are top-level “Global” hotkeys that work everywhere (e.g. opening dev menu with F11), lower level hotkeys that work in the game/maped and lowest-level ones that work only in gameplay/replay.

Army hotkeys were rigged, but I havent mapped default values to them.

There are also 2 new MapEd hotkeys to bring decals and map objects palettes now:

Refactoring Neutral hand and alliances

Making AI to attack neutral aggressive animals (and their dens) proved to be more complicated than I thought. Why is that?

Existing AI attacks work quite simple – AI has a list of attacks it needs to run at certain times (or periods), which are “nearest unit”, “nearest house”, “go to location”. Then AI checks if it has enough troops and launches the attack. To this time, I have planned for neutral hand to own both inert and hostile animals and houses. Which means that in order for AI to attack “any” enemy, it needs to check all enemy hands assets and also to check all neutral hand’s assets individually (to pick only hostile ones). Which is sub-optimal both from programming and from code-design point of view (especially the “individual” alliance setting).

Hence I’m looking into splitting neutral hand into two separate hands: inert and hostile, so that alliance settings between hands become simple again (either “ally” or “enemy”). Rules go like in order of priority:

  • Hand is always ally to itself
  • Neutral Inert hand (Ni) will be ally to anyone
  • Neutral Hostile hand (Nh) will be enemy for anyone (except self and inert)
  • All other alliances are governed by mapmaker and mission setup (except listed above)
  • And I get rid of that temp “it depends” alliance setting )

New problems arise though. Currently in Game and in MapEd all hands are tightly packed and each hand can be of any type atm. It’s a good time to fix this too. E.g. you can have 1 human hand and 7 separate neutral hands. Which is a waste of space really. Now there needs to be up to 2 different neutral hands – Ni and Nh (if hand has no assets it gets skipped). Still tightly packed on save and always on the right side of the hands palette in MapEd. Reordering hands is a bit complicated since hands hold a lot of cross-references (e.g. Goals/Objectives/Alliances/etc). Processing example goes like so: load a map into MapEd with 1/2/3/Nh hands. Append 8 more hands. Make the last hand Ni. Swap hands around for Ni and Nh to occupy the 11th and 12th slot. Do the map editing. Remove hands without assets before saving.

Another complication: previously I stored hand type in 2 fields in mission data: allowHuman and allowAI. 4 combinations of which described 4 hand types that were – Human, AI, Skirmish and Neutral. Now 5th type is needed, to split Neutral. For that I’m planning to add allowNeutralType flag/command.

There are other minor issues of course (and some bigger ones I haven’t stumbled upon yet), but overall I’m feeling confident and happy about this refactoring – it will make things a bit more complicated in one small area (Ni and Nh management),but much more simple in other broader areas (since larger parts of the game work with alliances).

On to the refactoring! )

2018 Christmas/NewYear mini-competition results

Mini-competition is over and I’m happy to announce the results!

We have 5 maps in the competition:

  • “Hodor” by Thibmo
  • “Longfingers Legacy” by Klassix
  • “Winter Stand” by Krom
  • “Xmas Tree Combat” by DarkianMaker
  • “Man Versus Man Versus Beast” by Eduardo Beltrame


Score 22.

Comments from judges:

  • Nice skirmish map
  • Nice map but approaches to camps are very wide for the size of the map

Longfingers Legacy

Score 22.5.

Comments from judges:

  • Very much like the details and usage of game assets
  • The maps looks OK, but please, less copy-pasta!
  • Would work well for a competitive map but could do with some more asymmetry. Could also do with a natural expansion of sorts for players to compete for

Winter Stand

Score 24.

Comments from judges:

  • The map looks great, nice addition for sure. Personally I would enjoy iron being available, though not all maps should have iron.
  • A lovely asynchronous map, but the river choke point is really too narrow for a proper fight against a defender

Xmas Tree Combat

Score 21.

Comments from judges:

  • Minimap and the whole idea look very nice to me. Simple and fun )
  • Very obvious X-mas reference. Haven’t seen a pure battle map yet, brings back KaM memories, bonus points for that. :smiley:

Man Versus Man Versus Beast

Score 21,67.

Comments from judges:

  • Unusual experimental map!
  • A very chaotic but interesting map, think it could’ve done with some more playtesting though
  • The amount of wolf dens…. wow. Interesting concept, too. But does need polishing.

Winners and prizes are:

  • 1st place with score 24  – Winter Stand by Krom
  • 2nd place with score 22,5 – Longfingers Legacy by Klassix (awarded Steam game of his choice (up to 15$ or equivalent))
  • 3rd place with score 22 – Hodor by Thibmo
  • All participants with maps scoring 20 or more – awarded with a small Steam game by Dah, called “You Can(Not) Survive”:

Food values

All Knights Province units need food to eat (well, except machines and animals). Otherwise they die of hunger. So dedicating a large portion of town to a food production is a good thing. But how much food is needed anyway? Let’s look into how much units eat:

Warriors can not leave their duty, so they get their food delivered by serf, which gets picked randomly in Camp/Store and tops warrior’s condition to 100%.

When citizen get hungry, they come to nearest Tavern that has free places inside (each Tavern can fit only 6 units at once). Typically when unit comes to Tavern he is at 13% full. When inside, unit will eat food in order it is listed in the Tavern until being 90% full.

I’ve been asked several times about food values for citizen, so here’s a small chart:

  • Fish – 0.5
  • Cider – 0.3
  • Bread – 0.4
  • Sausages – 0.6
  • Ale – 0.3

Please note, that above values are subject to change and should be considered correct only for current Alpha 9.1. In upcoming Alpha 10 values will be tweaked to:

  • Fish – 0.4
  • Cider – 0.2
  • Bread – 0.4
  • Sausages – 0.6
  • Ale – 0.3

So for example, in well stocked Tavern, unit will eat Fish+Cider+Bread and walk out, keeping Sausages and Ale intact.
