Four-directional building placement.

Post by Sean Mirrsen »

As some of you might know, I have been charged with the task of implementing into Spring the long sought-after function that would allow the rotation of buildings prior to ordering their placement. A lot fewer people, up until this moment at least, know that the making of this task has ended with an astonishing success:
Image
Note that buildings correctly display their orientation in build que, and the building's ghost following the cursor displays the current setting for building rotation. Factories have been tested and appear to be working fine, so do turrets and misc. structures. Rejoice!!! :D

Now somebody tell me what to do with the .diff...

lol ... your poll question sounds ... provocative :twisted:

Anyway i appreciate that you did this nearly "impossible-to-implement" task from the MTR :-)

Mail it to the mailinglist and ask if someone could review it for inclusion.
But maybe you could release a test version to see if there are things that still need to be improved?

Post what here? The diff? Or the exe? The diff is probably rather messy, since I still made a few random changes trying to determine the right sequence of events. And how would I upload the exe here?

The diff, we can probably see the basic idea from it directly.
I take your word for it that the exe works, so the question is if there are any problems with the code ;)

Also, when you found out how to rotate buildings, oculd you make random spinnage of for example solars in other than 90 degree incs? keeping yardmap etc..

There's probably a lot of useless and inefficient stuff there, but I guess it's my way of coding.

And you might be able to get the exe from http://edf.tauniverse.com/spring.exe, but only when the server no longer thinks it's exceeding the limit.

Comp1337: I might let buildAngle actually have an effect. ;)

Ok a couple of remarks:

- It seems you kindof hacked it in by modifying UnitDef::xsize and UnitDef::ysize when they are needed. This is not a clean solution. The unitdef shouldn't contain any temporary data. Better add things in a clean way directly. A proper solution for this is more work, but since you've already got a working version it shouldn't be that far away.
- As a more general idea, I think what spring needs is the concept of build information that is not part of the UnitDef itself. Right now this would only be buildFacing, but it might be more in the future. So you could solve it by passing around some BuildInfo structure that has xsize, ysize and buildFacing, instead of passing around the buildFacing setting.

Code: Select all

struct BuildInfo {
  UnitDef* def;
  int xsize, ysize, buildFacing;
};
Doesn't have to be exactly like this, as long as the idea is supported.
- Do rotated features work too? (For the destroyed rotated buildings)
- In builderCAI.cpp,

Code: Select all

        if(c.params[3]) 
            buildFacing=c.params[3];
should probably be

Code: Select all

        if(c.params.size()==4) 
            buildFacing=c.params[3];
The extra parameters for passing buildfacing must be optional, otherwise you'll break the AIs.

Other than that the code looks ok.

Also about the patch itself:
- The patch should have relative filenames, not absolute ones
- Be sure to upload the final patch it to a text file somewhere because the forum breaks lines.

good job man
also, could you add a "default orientatio" ?
for those who plan on N vs S maps, they may not want to bother rotating buildings every time they place one
tho, i havent try it so maybe you did it already .. or keep last orientation is ram

btw, if you wanna play with others, won't that cause unsync if everybody isn't using same exe ?

Did you read what he's said at all? It saves the last used orientation. Build something facing west and everything stays that way until you re-orient it.

And uhh, yeah, you'll have to wait for it to be packaged in an official release to use it online...

Very nice!

I know that minor features like this aren't as ultra-sexy as some of the things we have in Spring from the lead devs, but between you and ColorBlind, maybe we can get the "little stuff" done now that really seperates Spring from a truely polished gaming experience. Between the nice new explosions (I'm having waaaay too much fun with, btw) and everything else that's coming down the pipe, I am happy as a clam these days- now, if only I could get the latest version of NanoBlobs polished up enough to release... ;)

Some more comments on your patch:

Code: Select all

     }
Shouldn't the upper line be changed to if (c.params.size() < 4)? Or implement a separate check before assigning buildFacing (the fixed way as JC pointed out). Now it seems a bit inconsistent throughout the patch that sometimes you just assume c.params[3] is available, sometimes you check it is and default to 0, and other times you forget to check at all. (I could be a bit misguided because diffs only have 6 lines context per change tho, but check it :-))

Also you can eliminate/merge the switches by doing what JC says.

For the rest it looks good. Good work!

I don't know, but I think I made it that way because AIs can't currently send build orders with 4 parameters, and checking for 4 will break them. Or maybe I just forgot.. :P Speaking of which, still haven't tested it with an AI...

And just to clarify, JC, what was that you wanted me to do with buildFacing? Replace it with a buildInfo struct read from the same unitDef? Or what?
