Manipulating Sprays (Temp Entities)

[jimbodude]

Hello,

This is an extension of my thread here: [url]http://www.facepunch.com/threads/1051828-Manipulating-player-sprays[/url]

After trying various different ways to accomplish removing sprays, I've come to the conclusion this isn't possible. As far as I can tell, no extra entity is created server, or client side when someone sprays, thus, I can't see any way to remove the sprays.

A SourceMod plugin (sourcemod.net) can accomplish this, and it works just fine in GMod, but having a lua equivalent would be very nice. Plugin link (although down as of right now): [url]http://forums.alliedmods.net/showthread.php?p=665979[/url]

The SourceMod plugin makes use of Temp Entities, which uses the following for manipulating temp entities:

		"Offsets"
		{
			/* Offset into CBaseTempEntity constructor */
			"s_pTempEntities"
			{
				"windows"	"17"
			}
			"GetTEName"
			{
				"windows"	"4"
				"linux"		"4"
				"mac"		"4"
			}
			"GetTENext"
			{
				"windows"	"8"
				"linux"		"8"
				"mac"		"8"
			}
			"TE_GetServerClass"
			{
				"windows"	"0"
				"linux"		"0"
				"mac"		"0"
			}
		}

		"Signatures"
		{
			"CBaseTempEntity"
			{
				"library"	"server"
				"windows"	"\x8B\xC1\x8B\x4C\x24\x04\xC7\x00\x2A\x2A\x2A\x2A\x89\x48\x04\x8B\x15\x2A\x2A\x2A\x2A\x89\x50\x08\xA3\x2A\x2A\x2A\x2A\xC2\x04\x00"
			}
			"s_pTempEntities"
			{
				"library"	"server"
				"linux"		"@_ZN15CBaseTempEntity15s_pTempEntitiesE"
				"mac"		"@_ZN15CBaseTempEntity15s_pTempEntitiesE"
			}
		}

Perhaps a module, or some extra lua bindings could be created so we can do something similar?

You can remove them by using r_cleardecals twice, I wonder if there is a class for decals that could be ported to gmod lua.

You can remove/replace the basetexture of the spray texture and hence remove the spray. If I remember right.

Using r_cleardecals wouldn't be good for cleaning just one of them.

@FlapJack Really? How?

The basetexture of the spray should be temp/sprays/ something or other. If you get that texture, and then use SetMaterialString on it. I've never done it myself but it should theoretically work.

The problem I found with this is linking a spray to a player from those files. The file names are all weird and named differently on all clients and the server has a different folder where the sprays are held. Also I have never been able to display the client-side spray texture or server-side.

file.Time and link to the time sprayed possibly?

[Cardcapture1]

[QUOTE=Flapadar;27630775]file.Time and link to the time sprayed possibly?[/QUOTE] I was thinking of doing that. I think I might find problem when it comes to the client-side though because I don't see repeated spray files. I still see sprays from months ago.

I wonder if there is any linkage between the spray file name on my client 'a6cdc17c.vtf' and this file:

Could anybody find out?

[QUOTE=Cardcapture1;27631285]'a6cdc17c.vtf'[/QUOTE]

It's the file's CRC.

[Cardcapture1]

[QUOTE=Chrisaster;27631494]It's the file's CRC.[/QUOTE]
I checked for that already. It's not. I check a normal CRC32 checksum. Does Valve have it's own CRC check that's different from normal?

Why is was the first thing I check:

It might be the CRC of the compressed version.

SDK:

	// custom files CRC for this player
	CRC32_t			customFiles[MAX_CUSTOM_FILES];

This is where it gets the name from.

[editline]24th January 2011[/editline]

	char logohex[ 16 ];
	Q_binarytohex( (byte *)&info.customFiles[0], sizeof( info.customFiles[0] ), logohex, sizeof( logohex ) );

	// See if logo has been downloaded.
	char texname[ 512 ];
	Q_snprintf( texname, sizeof( texname ), "temp/%s", logohex );
	char fulltexname[ 512 ];
	Q_snprintf( fulltexname, sizeof( fulltexname ), "materials/temp/%s.vtf", logohex );

Thank you. :3
