Is it possible for a readable to display text in-game without being frobable?

 

edit: nvm, I fixed it by setting frob_distance to 1. Still technically frobable, but can't be reached.

It's a known bug; glad you found the workaround. It seems to be specific to GUIs using xdata, so if all you need is something like a signpost, a GUI material that accepts a gui_parm1 spawnarg as per https://wiki.thedarkmod.com/index.php?title=Text_Decals_for_Signs_etc. is another option.

It's more than just a signpost or a name on a plaque but it's just "flavour" text that I don't want to mislead the player into thinking is important by having it highlight. The text decals are fiddly, and at leas the readables editor shows you a preview of what it will look like.

[Destined 621]

Just out of curiosity: what happens, when you just make the readable unfrobable (via frobable 0)? Does it still show the text of the xdata? That way, you could circumvent the player acutally reading the readable, without your "hack" (the result should be the same, anyway).

[thebigh 102]

No, it does not show the text of the xdata on the model in/game. It's just a blank sheet. This is what I was actually trying to do: have the text visible on the model but without being able to get the readable popup by frobbing.

Trying to figure out DDS creation. The existing wiki entry by that name is pretty sad. For instance, it wants you to use a specific version of an obsolete, vendor-specific compression tool. I'm kinda sure anyone doing it now would use Photoshop or GIMP. Playing with latest GIMP, I'm guessing the setting might be, in the case where 100% opacity is desired:

1) Flatten Image (to merge layers and remove Alpha channel)
2) Use File/Export As, then in the Name field, change the file extension to .dds (must be lower case).
3) In the "Export as DDS" dialog, change these fields from their default values to new values:
- Compression: BC1/DXT1
- Mipmaps: Generate mipmaps
- Mipmap Options – Filter: Box

Could a DDS-GIMP expert here weigh in on these options, and whether one needs to change other things (sRGB, Gamma, etc.)?

I'd be happy to update the wiki about this when the dust clears.

Too bad; this would have been the simplest way, if it had worked. There is also the possibility to create Text Decals, which you can then apply to the model of the paper. Here is the Wiki page (recently updated by Geep) on how you can create them: https://wiki.thedarkmod.com/index.php?title=Text_Decals_for_Signs_etc. It is a bit mor complicated, so your method might still be better, but at least you know that there is a "proper" way.

[peter_spy 1603]

@Geep

At a first glance, the DDS entry needs rewriting or at least some restructuring. The comressonator bits are redundant, also there's no description on how DDS format works, or how dds files fit in the game folder structure. That should be in the first section, probably. Will try to take a look at it around the weekend.

@peter_spy, Thanks. I also thought a new first section was needed, and drafted a few paragraphs yesterday. I'll PM them to you for your consideration.

[Geep 266]

@peter_spy, oh, you're not taking PMs. Here's the text.
 

Spoiler

 

Here's what I came up with yesterday, until the brainpan wattage dimmed. Might be useful as a starting point, or at least the bits that are not delusional, based on what I (mis)remembered from some forum.

Possible modification to “DDS Creation”

== Why Pre-Create DDS Files? ==

The TDM game engine can read textures in either .tga (an uncompressed format) or .dds format. The compressed .dds format contains a hierarchical data structure, the same image at multiple resolutions. While that hierarchy is an impediment during image editing, at run-time it allows faster dynamic rendering of textures, by taking into account the distance of the viewer from a textured surface. This results in faster frame rates.

Nowadays, TDM makes fuller use of this .dds advantage: during startup loading, any textures that are only offered in .tga format are converted in memory to the .dds data structure. This conversion takes time and so leads to longer load times. Unfortunately, the converted files are not cached to disk, so this process must be repeated on every startup. [Is there some way to force the engine to save the DDS files? If so, this would be another, better way for the dev to generate them.]

To circumvent that, the FM creator can do the conversion and include it in the FM’s .pk4. The game engine will look first for a .dds to read directly, then, if unsuccessful, a .tga to read and convert.

The foregoing applies to a “diffuse map” texture (the main image) and its optional companion “specular map” texture. If there is also a “normal map” aka “bump map” texture, it should be left uncompressed in .tga form, typically 256x256 with no Alpha channel.

== Pre-requisites for Creating a DDS File ==

While traditionally a .tga is the starting point, any convenient image format can in theory be converted into a .dds, given the right software. The standard requirements for TDM’s DDS are:

The image is square, and a power of 2. Usually, it’s 512x512 (or 256x256 for specular)

If the diffuse texture has transparency, then a 32-bit RGB-Alpha format is needed. If opaque (or a specular map), then a 24-bit RGB format suffices. Note that the TDM engine supports only “hard edge” binary transparency, by applying a threshold value (default = 50%) against the 8-bit Alpha values.

== Generating an DDS in GIMP for a 100% Opaque Texture ==

Given an image that meets the pre-requisites,

Well, that's as far as I got. I wanted to revise this to tie in the standard file locations and texture file naming conventions, but couldn't decide how to make the text flow. A bit of content for that last incomplete "DDS in GIMP" section was suggested in my originally posted query. Other potential sections that could be useful but I couldn't write -

DDS in GIMP for a Texture with Transparency

DDS in Photoshop (with & without transparency; plugins?)

Batch conversions with GiMP; with Photoshop

Exceptions

(RE that, I just reported a bug about a material file's call to MakeIntensity(stain01b_s) throwing an error under 2.08. Response noted that it's .dds file, and image processing operations like MakeIntensity() only work on uncompressed files.)

 

 

[peter_spy 1603]

I don't? That's weird, I didn't change anything in PM settings in a long while.

Regarding the text, some bits here are good, but IMO it's a bit wordy, e.g. all content creators need to know about DDS format is that it's how images are stored in GPU (so there's no conversion during mission load), and that the compression ratio is very good (albeit lossy, so never work or on dds images). Still, that's a good start. I don't have anything on Photoshop, but I can cover DDS options for Gimp.

[Geep 266]

RE PM, maybe just a full in-box? Dunno.

Yeah, I agree that draft's a bit wordy. Looking forward to your GIMP coverage. Do you want to take the lead on the wiki page revision, or should I?

[peter_spy 1603]

I'm not English native, so maybe it will be better if I send you my part for editing / proofreading? Feel free to make the wiki revision

Btw. I'm not 100% sure on deleting the Compressonator part. I have an old and super-slow version, but a quick search revealed that it's still there. IMO it shouldn't be a first choice for mappers, as it's mostly for batch conversions (and that's not the best approach). GIMP is more accessible and DDS exporter is already its core component, so you don't have to search for plugins, and I'd rather encourage mappers to export to DDS simply when they're happy with a material. Going through dozens of files and choosing compression profile for transparency or gradients is more error prone than doing it on regular basis.

Speaking of readables, is there a way to make them appear on a specific layer? They show up "on top" of a gas mask overlay I've prepared, which breaks immersion somewhat.

[Destined 621]

Not sure, if this helps, but here is a Wiki article about overalys and layers: https://wiki.thedarkmod.com/index.php?title=GUI_Overlays

[thebigh 102]

Okay, so I'm putting the last few touches on my first map (YAY) but I cannot get the briefing text and objectives to show up. How do I do it?

According to the wiki, all I need to do for briefing text is to create a suitable xd file called briefing.xd in the xdata directory. In my case this would be \games\darkmod\fms\factory\xdata\briefing.xd since my actual map file is called \games\darkmod\fms\factory\maps\factory.map. The first line of the file is maps/factory/mission_briefing, and for now I just copied the rest of the stuff from Closemouthed Shadows since I know for sure that works.

Unfortunately, all I get when I start a new mission is a blank sheet. When I go to the objectives screen Darkmod crashes to a black screen and I cannot bring up the console. From the blank sheet briefing, if I go to the console I get the error "WARNING:DisplayBriefingPage: Could not find briefing xdata: maps//mission_briefing"

What am I doing wrong?

[Obsttorte 1524]

@RedNoodles: There is draw order and it can be manipulated, forgot how that works, though, but you should find the answer if you take a look at the gui files shipped with tdm (for example the compass is drawn over the objectives screen

@thebigh: Do you have a startingmap.txt file in your fm folder and the mission properly installed?

I think I must be the world's biggest dope.  I did have that, and it was called startingmap.txt.txt (thanks for that, Windows). Now that I fixed the suffix it is working as expected. Cheers!

[Obsttorte 1524]

Yep, that's my favourite mistake. That and typos.

I did some exploring and found the relevant lines in tdm_readables.script

Readables are rendered on layer # 10. The HUD is on layer #1. So the trick is to put the mask overlay above the readables, and below the HUD. By editing the "$player1.createOverlay" commands on tdm_readables I got the readables to render on layer # -1. after that I put my overlay on layer 0. Everything displays in the right order now.

 

[Obsttorte 1524]

Good. But looking through a plague mask would probably not appear like that (at least it doesn't look so with a gas mask, which is pretty close).

Quote

The textures used to be separated like that in the actual folder structure, but due to D3's inability to read .dds files five folders deep, they had to be moved.

FYI, that quote from the wiki doesn't seem to be true, I made both a path that has 8 folders in total, and I also used fairly long names (over 150 characters total). I'd rather suspect there's a character limit for paths, but I've yet to hit it. Both 32 and 64 bit version have no problems with more than 5 folders.

thanks, but just to clarify I didn't make that. I'm using the default TDM spyglass overlay. originally i was going to use a thick glass texture and an air filter system (each filter would last 30 seconds or so) but they made navigation too difficult

[Bienie 424]

I'm having some trouble with pathing. I'm teleporting in some AI to fight some other AI, they are then to assume the same patrol route as the people they killed. Some of them work fine, but others will just stand there after the fight and not ever go back to patrolling. The way I set it up is to use a atdm:target_changetarget one second after they are teleported from the blue room, and they all assume patrols as they should, but only for a few seconds before they see the other AI and start fighting. Is the fighting somehow breaking their patrols? Can this be avoided or remedied somehow?

[Obsttorte 1524]

The default behaviour should be that the ai continues to patrol after the fight has done and it has calmed down (the latter might take a while). If the ai is not resuming the patrol then one possibility is that it may has issues reaching the next path_corner. Are there any warnings/error messages in the console?
