Speedometer

[Hypersonic]

Does one come with the engine, or is there a mod? It would be nice to verify being in run mode (not walk), and to see the speed difference with dual chording.

What?

Some examples in Quake 3

Quickly cooked something up - https://www.dropbox.com/s/2okixyv2du8wp ... r.pk3?dl=0. Doesn't have all those crazy bars that the first video has, because I have no idea what those mean . Also includes some information about angle, pitch, yaw, and position, feel free to take those out of the code if you just want speed.

Great example for learning the possibilities of ZScript (wiki worthy)

[Gutawer]

I'm not sure about that, the code was thrown together really quickly, and there's probably a bunch of ways it could be improved (I don't really like having to use DTA_HUDRules, but AFAIK it's the only way to get stuff to scale to the HUD size - my problem is that it draws from the top middle rather than the top right) .

I just want to point out how great it is that a user named Hypersonic has requested a Speedometer.

Improvement on details is always possible, but since ZScript code examples are yet difficult to find, this is surely an example that can give people a start!

[Hypersonic]

Thanks for putting it together Gutawer! The extra info could come in handy as well (though idmypos 1 already displays position.) I haven't tried it just yet, but I'm curious about how ZScript works. Is it compiled at run time like Javascript, or pre-compiled such as Quake 1 (.qc files compiles to a progs.dat file.)

In the pk3 (zip) file I see 2 files

.lmp (adds event handler)
.zsc (defines an event handler)

(Ya I'm not sure what the bars in the first video are either, presumably something to assist one learning to strafe jump in Quake 3.)

EDIT: didn't know .lmp was a text file, thought it was binary. So there is no pre-compiled code.

[Gutawer]

Yeah, .lmp is just the extension I use for lumps that aren't quite code, but aren't plain English text files either.

Tried to run it, but nothing seems to happen, even when not using advanced hub. Using GZDoom 3.1.0.

About HUD scaling: since I took your Speedometer as one of the examples to learn more about ZScript, I found out that the Screen.DrawText you use has a lot of flags.
DTA_KeepRatio & DTA_VirtualWidth / Height are quite powerful concerning scaling:

Code: Select all

// title top middle of the screen
string sTitle = "=title=";  
Font fnt = bigfont;
Screen.drawText(fnt, Font.CR_OLIVE, 320 - (fnt.StringWidth(sTitle) / 2), 1, sTitle,
	DTA_KeepRatio, true, DTA_VirtualWidth, 640, DTA_VirtualHeight, 400);

// stuff top right corner of the screen
string stuff = "=stuff=";
Screen.drawText(fnt, Font.CR_DARKBROWN, 640 - (fnt.StringWidth(stuff) +1), 1, stuff,
	DTA_KeepRatio, true, DTA_VirtualWidth, 640, DTA_VirtualHeight, 400);

[Gutawer]

I'm aware of those, but I wanted to keep the text scaled to the user's HUD scale preferences.

[gwHero]

I see what you mean, the font is scaled automatically.

Btw, since I have recently read this discussion viewtopic.php?f=3&t=55278 from a while ago, I am now fully aware of the efforts the developers have made to make this all possible. Even more, apparently Graf was very reluctant in the beginning to give renderoverlay to the modders since it could quite mess with the playsim.

But I guess we can freely use it now to display messages and simple stuff on the screen? Or is using the statusbar classes a more preferred way to show things on the screen?

EDIT: About using it safely is answered here I guess https://zdoom.org/Changelog/1dcc017da/files
