AttachEffectToObject [Solved]

MetalcoreRancor · Post by **MetalcoreRancor** » Wed Jan 20, 2010 8:29 pm

I looked using the swbf2 script finder, and used search on GT, only to find nothing helpful on this.

I need to know how to use this lua function so I can attach an effect to tomb stones to visually mark progress of waves in my zombie mod. So I would insert AttachEffectToObject(objectname, effectname)? into each wave to mark them? Any help would be appreciated.

Can't you just have a changing msh that changes to one with more marks according to the waves that have past?

Hmmm, that command might also need a hard point on the msh...but AttachEffectToMatrix works well"

Code: Select all

AttachEffectToMatrix(CreateEffect("fel_sfx_springmist"), GetEntityMatrix("Tombstone"))

You will have to modify the effect's position in the effects editor, or shift the matrix's location (geometrically 'translate' it) on the matrix as such:

Code: Select all

MatrixData = GetEntityMatrix("TombStone") --Grab and store Tombstones location (matrix) in "MatrixData"
MatrixData = CreateMatrix("0,0,0,0,0,0,2, MatrixData")  -- Reset Matrix data to be old Matrix Data but 2 world units higher.

as shown in this thread:

So I place
AttachEffectToMatrix(CreateEffect("com_sfx_wavecomplete"), GetEntityMatrix("neu_bldg_luatomb"))
MatrixData = GetEntityMatrix("neu_bldg_luatomb")
MatrixData = CreateMatrix("0,0,0,0,0,0,2, MatrixData")

In each wave, replacing luatomb with the various object numbers, and it should work each time a wave starts?

-Edit-

I'd really appreciate a response, because this coding did not work.

Something like that, though I'm not familiar with your code, and if you want to use the second to lines instead of editing the effect, then you need to change the first line to have "MatrixData" instead of "GetEntity Matrix", employed in this order:

MatrixData = GetEntityMatrix("neu_bldg_luatomb")
MatrixData = CreateMatrix("0, 0, 0, 0, 0, 0, 2, MatrixData")
AttachEffectToMatrix(CreateEffect("com_sfx_wavecomplete"), MatrixData)

Oh, and you'll need to toy with the numbers in Create Matrix. Start with smaller values I think, like 0.5...

Thanks for the quick response. Ill try to incorporate that, but what do the numbers mean? Is it coordinates or the number of times used? I'm going to be copying this set of lines 30 times, 1 for each wave.

I dun linked that thing up - thread linked in my first post, but its basically Create(Rotate X*, Rotate X, Rotate Y, Rotate Z, Move X, Move Y, Move Z, StartingPointMatrix) from what I understand.

It still did not work, so Ill post a reference sample of one wave.

Code: Select all

  
    wtime0 = OnTimerElapse(                
    	function(timer)
    		StartTimer(wavetimer0)
    		ShowTimer(nil)
    		ShowTimer(wavetimer0)
    		ShowMessageText("level.dea1.zombie") 
zombiehorde = math.random(3)
			if zombiehorde == 1 then    
    		Ambush("CP5Spawn", 2, 6)
    		Ambush("CP5Spawn", 2, 6)
    		Ambush("CP5Spawn", 2, 6)
    		Ambush("CP5Spawn", 2, 6)
    		Ambush("CP5Spawn", 2, 6)
    		Ambush("CP5Spawn", 2, 6)
    		Ambush("CP5Spawn", 2, 6) 
    		Ambush("CP5Spawn", 2, 6)
    		Ambush("CP5Spawn", 2, 6)
    		Ambush("CP5Spawn", 2, 6)
    		Ambush("CP5Spawn", 2, 6)
    		Ambush("CP5Spawn", 2, 6)
    		Ambush("CP5Spawn", 2, 6)
			 elseif zombiehorde == 2 then
    		Ambush("CP1Spawn", 2, 6)
    		Ambush("CP1Spawn", 2, 6)
    		Ambush("CP1Spawn", 2, 6)
    		Ambush("CP1Spawn", 2, 6)
    		Ambush("CP1Spawn", 2, 6)
    		Ambush("CP1Spawn", 2, 6)
    		Ambush("CP1Spawn", 2, 6) 
    		Ambush("CP1Spawn", 2, 6)
    		Ambush("CP1Spawn", 2, 6)
    		Ambush("CP1Spawn", 2, 6)
    		Ambush("CP1Spawn", 2, 6)
    		Ambush("CP1Spawn", 2, 6)
    		Ambush("CP1Spawn", 2, 6)
			 elseif zombiehorde == 3 then
    		Ambush("CP4Spawn", 2, 6)
    		Ambush("CP4Spawn", 2, 6)
    		Ambush("CP4Spawn", 2, 6)
    		Ambush("CP4Spawn", 2, 6)
    		Ambush("CP4Spawn", 2, 6)
    		Ambush("CP4Spawn", 2, 6)
    		Ambush("CP4Spawn", 2, 6) 
    		Ambush("CP4Spawn", 2, 6)
    		Ambush("CP4Spawn", 2, 6)
    		Ambush("CP4Spawn", 2, 6)
    		Ambush("CP4Spawn", 2, 6)
    		Ambush("CP4Spawn", 2, 6)
    		Ambush("CP4Spawn", 2, 6)
           end	--neu_bldg_luatomb
   MatrixData = GetEntityMatrix("neu_bldg_luatomb")
    MatrixData = CreateMatrix("0, 0, 0, 0, 0, 0, 1.0, MatrixData")
      AttachEffectToMatrix(CreateEffect("com_sfx_wavecomplete"), MatrixData)

			DestroyTimer(timer)	
            end,
        wavetimer
        )

I should admit now that I'm rusty with LUA and SWBF2 in general but:
First of all, check BF2log for references to the effect (maybe its not being found...
***I just remembered, it seems that an effect must be loaded up using and odf with a hitpoint, like some of the foggy dagobah trees etc. This must be done or else they aren't loaded for use. Might be a better way, but on my map I just placed a hidden object - a tree with a bunch of light effects on it as well as a giant plume of starship exhaust blasting it out from it lmao) Failing that ***
....make sure that its not just being placed below the map or something, and add a
print("Effect code ran")
command beside the effects stuff, so that the log file will print it out if the code in the area of the lua is even running.

But I'm pretty sure its that the fx file needs to be attached to an object via its odf file, then the effect can be added to random tombstones.

BTW, I've never had success removing or moving an effect. It might be able to be done but IDK.

Sure enough

Message Severity: 2
.\Source\LuaCallbacks_Mission.cpp(635)
Entity "neu_bldg_luatomb" not found

Now.. I wonder how to work this >.<

-edit-

After talking to Fiodis, he showed me the FAQ topic you made on this ages ago, and Ive encorporated a similiar system, but I still have:

Message Severity: 2
.\Source\LuaCallbacks_Mission.cpp(635)
Entity "neu_bldg_luatomb" not found

and each wave has:

Message Severity: 2
.\Source\LuaCallbacks_Mission.cpp(4519)
Effect class "com_sfx_wavecomplete" not found

-edit-

works now. Luatomb was supposed to be luatomb1.
