i think it should be instant... depending on the delay, you can lay the same thing quicker.... also, you can instantly place REALLY long sections of tracks, if you use an AI type delay, it would definitly take longer to duplicate long stretches of tracks, why duplicate long stretched of tracks? maybe the long stretch of tracks holds cross over sections, and junctions that you might want copying at regular intervals.

am i correct in assuming that the copy paste acts like a clipboard, so once you copy the junction you can place it multiple times, untill you select another section to copy?

Rotation won't be easy with (non-square) airports, and with newstations - some of which aren't properly rotatable (such as the Toronto Grand Central one).

I'm intreted to know how the copy feature deals, or will deal, with objects which extend beyond the selected area. Examples include the selection just covering part of a larger station, covering part of an airport, or one end of a long tunnel.

Trainstations can be cutted into smaller ones. Not clever but it works.
Copy only half of an airports will crash the game i think. On the other side is it clever to copy only half of an airport? So i think the copy function only should copy the airport if the whole airport is copied. The same to tunnels.
Rotating an airport wont work too. So then it should not be copied too.
Something left what can't be rotated?

@bobingabout:
Yes you may copy it more than once.

@delay questions:
Maybe there will be different types of copy&paste.
I will come back to those ideas later.

@Brianetta & gigajum:
Objects which are not completely inside the copied area, are not copied.
(Currently applies to Bridges+Tunnels)

If anyone wants to play around,
here is the patch + compiled windows exe.

Stations, especially non-uniform stations will require some thinking,
so this will take a while.

Current todo list:

-check tunnel-end out of selection
-check terrain before tunnel build
-implement Stations
-implement Depots
-implement Waypoints

One problem will always be that this patch depends on nearly all game structures. So if anything changes or gets added, this patch must be updated too.

EDIT:
Maybe someone should move this thread to developement.

Some questions:

Why are you taking 7 arrays to store the information? Why not copy tile for tile into a small copy array of struct Tile. And only check tile for beeing copied or left out. And the past function builds exact the copy array onto the map.

Why are 100x100 tiles copyable? Aren't 16x16 or 32x32 (maximal) enough?

Depends what you want to copy. If you're trying to spare the effort of duplicating a huge junction, you might need a huge copy buffer.

No comment on your first point, though, as I dont have the background.

huge junction? how big? 32 tiles are about 2 screens in 800x600. with 100x100 you can copy a whole 64x64 map and almost the whole 128x128 map. if would copy something i copy that within the screen since i need to fit that copy into the destination tiles. But with 10000 tiles where is the meaning? it's waste of RAM, imo. 16x16 should be enough. if something is missing, copy the missing part, too.

The tile struct uses 8Byte,
At the moment the 6 arrays I use also take 8Byte per tile.

10000 * 8Byte is around 80kb, which is not that great memory waste.
Some of my junctions are larger than 32x32, so I decided to raise the
maximum from 1000 to 10000.
But maybe 50*50 is enough, which would be 20kb of RAM.

The tileheight(difference) needs to be stored for every tile.

I did not directly copy the tile-struct, to be somewhat independent from the map array. Which I noticed later, is futile anyway.

10000* 8Bytes * 6 array!!!!
so it is not 80KB it is ~470KB
ok the computers today have enough of that, that's not the problem. i only wanted to know why

If you have 50x50 junctions you could copy more single parts. 32x32 are big enough (imo)

Frostregen · Post by **Frostregen** » 20 May 2006 12:43

The 8Bytes are for all 6 Arrays.

Code: Select all

int8 _copy_heightmap[COPY_MAX];      
uint8 _copy_rail[COPY_MAX];   
uint8 _copy_tunnel[COPY_MAX];      
uint8 _copy_road[COPY_MAX];        
uint16 _copy_signals[COPY_MAX]; 
uint16 _copy_bridge[COPY_MAX];

1 + 1 + 1 + 1 + 2 +2 = 8

NOTE:
In the sourcecode, the calculation is wrong.
It should read:

Code: Select all

//Total Space used = 8 * COPY_MAX = 80kb

Somehow i counted the bits, instead of bytes

What means:

"ERROR: Invalid version of language packs" ?

I loaded the last Nightly and replaced the openttd.exe with this one of this topic.

Greetings EBI

gigajum · Post by **gigajum** » 20 May 2006 13:06

uhm yeah ... your right, i'm busy with something other and only read over and remembered the 640KB usage. But as said that's not the big problem with the ram usage.

@ Ebi

The IN uses other lang files then the normal nightly. So get the lang files from the nightly around r4914

ebi · Post by **ebi** » 20 May 2006 13:39

Hello,

so, i tried to use the Mini Integrated Nightly with this openttd.exe but Error too. And the file size are totaly different. I'm desperate.

Greetings EBI

Frostregen · Post by **Frostregen** » 20 May 2006 16:27

Here are the lang files...

Thank You, Its running and the feature is great!!!!

bobingabout · Post by **bobingabout** » 21 May 2006 19:47

i want to be able to copy something like this

Frostregen · Post by **Frostregen** » 22 May 2006 03:45

@bobingabout:
This is already possible

At the moment I am coding a gui.

If you have 50x50 junctions you could copy more single parts. 32x32 are big enough (imo)

This will be a problem with tunnels/bridges which are only partially contained.
They would be left out. Anyway this is finetuning, which will be something to think about later.

Haukinger · Post by **Haukinger** » 22 May 2006 17:18

Can you select diagonally ? Or are mountains in the corners of bobingabout's junction copied with the junction ?
Perhaps it is possible to add an option that it copies only 'modified' tiles, that is, thoppse with tracks, tunnels bridges etc. on them...

Frostregen · Post by **Frostregen** » 23 May 2006 03:23

@Haukinger:
Good point, I'll try to make this an option
