FHS`s NFO problems thread

[FHS]

Hello, I have a little problem.

It seems that I can get the code to work, however, nothing appears. All eight directions are blank in the game.
I just followed the tutorial at: "http://wiki.ttdpatch.net/tiki-index.php ... rstVehicle". It just draws white blanks in all views in the game.

I will send a PM on request with the sprites I used. I cannot post them openly because of copyright, however, I am not completely sure about that.

Look at your coordinates of those sprites. Sprite #3 has its upper left pixel at x=1, y=8 and extends to x=9 and y=26 (width=8, height=18) in first.pcx. Given the size in width and height of those sprites, all your x/y coordinates of the upper left pixel of the sprites seem to be wrong.

How can I solve the problem?

[planetmaker]

Uhm... specify the proper positions where your sprites are found in your PCX? I don't really know how to explain it differently than in my previous posting.
E.g. your 2nd sprite is just ONE pixel to the right of the upper left pixel of the 1st one: upper left pixel (x/y) = (2/8) to lower right pixel (x/y) = (22/27). They overlap ~90% and probably it's all white in your PCX. The bad part of non-free licenses is that we cannot really help in place Kick your artists to supply proper licensed drawings.

[FHS]

Thank you, just got it to work.

Kick your artists to supply proper licensed drawings.

I cannot kick Simon Foster, can I. Because I followed the tutorial I decoded trg1r.grf and used a sprite from there.

Instead of decoding trg1r.grf and working from there you could also decode one of the opengfx base grfs. Then you would be able to post the pcx and nfo here to ask for help (provided you don't mind your nfo is also released under gpl, but I assume that for some testing that is no problem at all).

[FHS]

I plan to use nfo only to encode a couple of private grfs.
I am afraid I will not release them for the general public unless I consider them finished.
They are too small to be interesting anyways.

I'm not sure if I've pointed this out before, but GPL licencing is not automatic; FHS can modify OpenGFX and post it without what he posts being licenced under the GPL, although in doing so he will of course be breaching the OpenGFX licence (so please don't ).

A couple more things,

Firstly, while the OTTD moderators are incredibly fussy about people posting even one copyrighted pixel, I personally consider the original TTD sprites to be fair game, so don't worry about posting a few here if it will help.

Secondly, if you want to draw your own train sprites, I recommend my sprite templates. It will save you a lot of headaches with working out sprite offsets.

[FHS]

Thx Pikka. But I already have my sprites since a rather long time.
And at the moment I am rather focusing on successfully coding two engines in one grf.
But still, Thx.
