Official KaM Remake Bugs topic

Yes, It's lagging very much at 1x speed. I have to wait 5-10 secs and the game runs normally for some seconds and it starts again.

[Krom]

Yes, this is a known bug caused by too many troops moving all at once (requesting routes to be assembled across whole map). We are still thinking on optimizing our road building algorithms...

[kocsis1david]

What kind of algorithm does it use? And can you tell me how fast is it approximately to go e.g. from top left to top right in large map?

[Krom]

We use A* on a map that was ConnectedComponentLabeled. So that before running A* we know if route A-B exists. The thing is A* is executed for EACH unit in a group separately. When executed our A* also takes into account if there are units on a tile, they add additional cost to the route (that helps serfs to take less crowded routes in towns).

[kocsis1david]

I have an idea which would take about 0.1 ms to find a long route maybe even less, I think I'll implement it soon to tell a more accurate time if that time is good, but I don't think it would be very good for serfs.

[Krom]

You can outline your idea here, maybe I can point out weak spots at once.

[kocsis1david]

A navigation mesh will be needed (outside from the path finding):


The routes between points also have to be pre-calculated. This would be a simple path that doesn't goes over any point of the navigation mesh and only goes in 2 directions (a diagonal and a not diagonal) with max. one turn. It can be specified by the difference of the coordinates. e.g. if x2 - x1 == 1 and y2 - y1 == 5: it has to go one tile in right-down direction and 4 tile down.


I think A* can be used to find the shortest path in the graph, there are much less nodes now than if every tile is a node.
When a tile becomes walkable or unwalkable the navigation mesh has to be changed with minimal amount of calculation otherwise it would also be slow.

[Krom]

1. NavMesh, okay.

2-3. Routes between NavMesh vertices ... Units do walk from one side to another quite often (at least armies), but I don't see how making list of all possible connections helps us. E.g. put the orange point 1 tile up.

I imagine A* pathfinding like walking in a room without a light and being able to "see" walls only by hand. So point 1 you stand somewhere and you know your target is somewhere else. You walk 1 step and you check if there's wall and how far your target is now. If you hit a wall you return to step where target was closest and there were no walls and keep on trying till you reach it.

Now take pic3, I'm a orange dot, how do I know of any NavMesh graphs? and how would following one line connecting NavMesh vertices would help me to get to the target.

[kocsis1david]

The routes between the nodes are quite cheap to compute, and it can be calculated when the map loads. When the road is needed a virtual point will be added to the navigation mesh. And then you only need to walk through that graph with some fast weighted graph search algorithm.

This might or might not be a big, but when I was playing the Town Tutorial today (I just like randomly playing it for the city builder aspect ), I suddenly got this message:

This might or might not be a big, but when I was playing the Town Tutorial today (I just like randomly playing it for the city builder aspect ), I suddenly got this message:

That certainly is a bug, one of the tutorial messages could not be loaded for some reason. Could you please give us some more information?
- Were there messages before it and were they correct? The messages usually appear after you construct a building or defeat the enemy to tell you what to do next. Do you remember what the last thing you did was? (or approximately what stage you were at)
- Did you start it from the Town Tutorial button or did you load a save of the tutorial? (or maybe with the Restart button on the results screen?)
- Had you been playing any other games/missions before this one since you started the KaM Remake?

If you could find the log file from that occasion (in the Logs folder, they have time/date stamps from when the Remake was started) that might also help us.
Cheers,
Lewin.

Hmm... There certainly were correct messages before it, but all the ones afterwards gave this same error code. I didn't add that in the original message, as I immediately made the screenshot when I saw it, posted it to the forums and continued playing again.

- Did you start it from the Town Tutorial button or did you load a save of the tutorial? (or maybe with the Restart button on the results screen?)

I'm pretty certain that this was from the Town Tutorial button.

- Had you been playing any other games/missions before this one since you started the KaM Remake?

No, I think this is was the first one. I didn't play multiplayer at all, but I think this was the first one.

If you could find the log file from that occasion (in the Logs folder, they have time/date stamps from when the Remake was started) that might also help us.

Judging from the time I posted the message, this should be the right one. The title is KaM_2012-07-08_19-10-26-484.log:

Terrain bug. Compare how it looks in Krom's editor (first picture) and in KaM Remake (second picture). I'm sure it has to do with heights: if I make the terrain more even it looks how it is supposed to, but as soon as there is a slight height difference like here, KaM Remake seems to mess up the shades.

There is a known bug in r3392 around water, there are square edges around tiles that are darkened due to shading at the edge of the water. Krom fixed it a few weeks ago If you have any problems like this not in water let us know.

On a side note water will not look exactly the same in the Remake and Krom's editor, because Krom's editor doesn't draw underwater sand hills like in KaM. Here's an example of sand hills in KaM and the Remake: (this image is quite old, our sand hills have changed/improved since then)

If you look in Krom's editor you won't see those sand hills at all.

[The Dark Lord]

I know about the sand hills but if I remember correctly they shouldn't be there at all when we're talking about the 'grassy water'. Glad this is fixed though, it looks pretty ugly.
