Restrict Certain Props

[Thud13]

Was just curious- people on my server have the new hobby of crashing my server with explosive barrels. Its annoying, and I can't do anything about it.

And I was wondering if this feature was already built in:

Is it possible to create a way to limit the amount of explosive barrels that can be created? 10 Barrels max IMO would be a good number.

If it doesn't have this feature built in, could anyone point me in the right direction to code up something simple? Its really becoming an issue fast.

Here's a very basic one..

Code: Lua

1. local models = {}
2.  
3. function restrictProp( prop, number )
4.         models[ prop ] = number
5. end
6.  
7. local function blockProps( ply, mdl )
8.         if not models[ mdl ] then return end -- Not blocked
9.         ply.mdlCount = ply.mdlCount or {}
10.         ply.mdlCount[ mdl ] = ply.mdlCount[ mdl ] or 0
11.         if ply.mdlCount[ mdl ] >= models[ mdl ] then ply:PrintMessage( 3, "You're over your limit for this prop!" ) return false end
12.         ply.mdlCount[ mdl ] = ply.mdlCount[ mdl ] + 1
13. end
14. hook.Add( "PlayerSpawnProp", "blockProps", blockProps )
15. restrictProp( "models/props_c17/oildrum001_explosive.mdl", 10 )
16.  

Doh, just realized this code won't free the numbers as the prop is deleted, but the gmod wiki is down right now so I can't look up the hook. I'll fix it when it's back up.

You guys are really awesome. Thank you for being so kind.

Okay, here's the final version of this quick hack.

Code: Lua

1. local models = {}
2.  
3. function restrictProp( prop, number )
4.         models[ prop ] = number
5. end
6.  
7. local function blockProps( ply, mdl )
8.         if not models[ mdl ] then return end -- Not blocked
9.         ply.mdlCount = ply.mdlCount or {}
10.         ply.mdlCount[ mdl ] = ply.mdlCount[ mdl ] or 0
11.         if ply.mdlCount[ mdl ] >= models[ mdl ] then
12.                 ply:PrintMessage( 3, "You have reached the limit for this prop (" .. models[ mdl ] .. ")" )
13.                 return false
14.         end
15.         ply.mdlCount[ mdl ] = ply.mdlCount[ mdl ] + 1
16. end
17. hook.Add( "PlayerSpawnProp", "block.blockProps", blockProps )
18.  
19. local function recordProps( ply, mdl, ent )
20.         if not models[ mdl ] then return end -- Not blocked
21.         ent.blockOwner = ply
22. end
23. hook.Add( "PlayerSpawnedProp", "block.recordProps", recordProps )
24.  
25. local function propRemoved( ent )
26.         if ent.blockOwner then
27.                 local mdl = ent:GetModel()
28.                 local ply = ent.blockOwner
29.                 ply.mdlCount[ mdl ] = ply.mdlCount[ mdl ] - 1
30.         end
31. end
32. hook.Add( "EntityRemoved", "block.entRemoved", propRemoved )
33.  
34. local function tool( ply, tr, toolmode )
35.         if toolmode == "magnetise" and tr.Entity.blockOwner then
36.                 ply:PrintMessage( 3, "You cannot magnetize this prop, sorry." )
37.                 return false
38.         end
39. end
40. hook.Add( "CanTool", "ULXToolCheck", tool )
41.  
42. restrictProp( "models/props_c17/oildrum001_explosive.mdl", 10 )

Just call the restrictProp() function with what you want. Note that a really easy way to get around this protection is to rejoin... but hey, we're going for simple here.

I'm trying to call the restrictProp() function in multiple lines for various props like this:

Code: [Select]

...
restrictProp( "models/props_c17/oildrum001_explosive.mdl", 5 )
restrictProp( "addons/phx/models/props_phx/amraam.mdl", 2 )
restrictProp( "addons/phx/models/props_phx/torpedo.mdl", 2 )
But I must not be able to "see" the addons/phx/models/props_phx folder, because this restriction for the phx models is not working. The restriction on the oildrum works however. Can anyone help me on this? I have tried various ways without success. Thanks for any tips.

EDIT: Nevermind I figured it out. The problem was in my path. Below is the correct way, noting the extra forwardslash as being what solved it for me:

Code: [Select]

...
restrictProp( "models/props_c17/oildrum001_explosive.mdl", 5 )
restrictProp( "addons/phx/models//props_phx/amraam.mdl", 2 )
restrictProp( "addons/phx/models//props_phx/torpedo.mdl", 2 )

[Megiddo]

Hmm odd, I'd think that you'd drop the addons/phx/ part entirely.

[Dr.Roxor]

Perhaps it works both ways. I know it is working as shown in my snippet above.
