Problem with Sprites - Solved

[lukas]

This problem is solved. Thanks Gez, Enjay and Zippy for your help.

While working on my first mod - Operation Super Soldat - http://forum.zdoom.org/viewtopic.php?f=19&t=25511, I encountered this problem.
When I import this sprite in the game,
It appears ingame like this:


Any help with this will be greatly appreciated.

Cyan is not transparent.

Use something like the Gimp or Irfanview to make the cyan area actually transparent, and save as a PNG. Then import that PNG again.

Thanks. I'll try that.

EDIT - Didn't work. Here's the PNG with transparency (I made the background transparent with GIMP) and how it appears ingame




EDIT 2 - I didn't mention it before, but maybe it has something to do with the fact that the sprites were made in Wolf3d palette. I don't know how to make them work with Doom palette.

[Gez]

It works for me:

[Enjay]

Looks like whatever you are using to put it into your WAD/zip is forcing it into the Doom palette and ruining the transparency at the same time.

Try the attached (obviously I only has one frame so they don't do anything).

nazi.zip

Of course, although I used a WAD, you don't have to put things into WADs at all. If you use the zip structure, you may find it easier.

Thanks for the help, both of you.

Your sprites work, which is very strange because they seem almost identical to mine.

I will compare your and my sprites in GIMP to see what's the difference.

[Gez]

I made no changes to it, except to give it offsets with SLADE3 (that's the [wiki]grAb[/wiki] chunk). Image data is unmodified.

I just don't get it. The sprites are the same.

I've tried everything, and still my sprites just won't work.

If it's not too much trouble, could you describe step-by-step how to make the background transparent with Gimp. Maybe I'm doing something wrong there.

[Gez]

But, as I tell you, I have used your sprite.

The question is not about how to make it transparent, it IS transparent. The question is actually "how to you import this graphic into a wad file". Because it is there that the problem happens.

I'm going to guess that you're not using Slumped or Slade3.

[lukas]

I use XWE for importing graphics. But I'll try slade and slumped - maybe that's the problem.

EDIT - I tried using slumped and it works!
Thanks for the help, Gez.

[Zippy]

For the record, to load PNGs in XWE you need to use Entry->Load (Raw). Once it's loaded like that XWE will recognize it as a PNG and tell you so when you select it in the lump list, and let you change the offsets, etc.

[lukas]

Oh, so that's the problem. I always import sprites with Entry->Load.
Thanks Zippy.

[Enjay]

I made no changes to it, except to give it offsets with SLADE3 (that's the [wiki]grAb[/wiki] chunk). Image data is unmodified.

And just for the record

I made no changes to it, except to give it offsets with grabPNG. Image data is unmodified.



Also @ lukas for future reference, it is preferred if you do not edit your first post to remove the question. someone else may come along with the same question as you but now they can't easily see what you asked.

OK, I'll edit the first post and put back the question along with a note that the problem is solved.
