[HELP] Matrix rotation - position problem

[Incama]

Hello everyone!

 

So i'm trying to make a script that places a object in front of the player.

Problem is: 
I have everything client sided and i stream the object with a simple create function and elementDatas (streamin, streamout, elementdatachange),

but everytime that it asks for the player's (not localPlayer) position it doesn't take into count the rotation of the player (not localPlayer). For me it places it in the right places, but for other people it shows in way if i would have 0 rotation.

 

I'm using matrixs and transformPosition. Any idea?

 

(i've tryed asking for the localPlayer.matrix and source.matrix in the runcode resource and it indicates everything well)

Use this

local pos = localPlayer.matrix:transformPosition(Vector3(0, 2, 0))

 

[Incama]

local bobbers = {}
local lines = {}

function start()
	setElementData(localPlayer, "bobber:create", true)
end

function createBobber(player, m)
	if m then
		if not bobbers[player] then
			local m = player.matrix:transformPosition(Vector3(0,math.random(3,10),0))
			local z = getWaterLevel(m[1], m[2], m[3]) or -0.55
			bobbers[player] = createObject(1974,m[1], m[2], z)
			setObjectScale(bobbers[player], 2)
			lines[player] = true
		end
	else
		if isElement(bobbers[player]) then
			destroyElement(bobbers[player])
			bobbers[player] = false
			lines[player] = false
		end
	end
end

addEventHandler("onClientResourceStop", resourceRoot, function()
	if getElementData(localPlayer, "bobber:create") then
		setElementData(localPlayer, "bobber:create", false)
	end
end)

addEventHandler("onClientElementDataChange", root, function(data, oldv) 
	if data == "bobber:create" then
		if isElement(source) and getElementType(source) == "player" and isElementStreamedIn(source) then
			local m = getElementData(source, "bobber:create") or false
			createBobber(source, m)
		end
	end
end)

addEventHandler("onClientElementStreamIn", root, function()
	if isElement(source) and getElementType(source) == "player" and getElementData(source, "bobber:create") then
		if source ~= localPlayer then
			local m = getElementData(source, "bobber:create") or false
			if m then
				createBobber(source, true)
			end
		end
	end
end)

addEventHandler("onClientElementStreamOut", root, function()
	if isElement(source) and getElementType(source) == "player" and getElementData(source, "bobber:create") then
		if source ~= localPlayer then
			local m = getElementData(source, "bobber:create") or false
			if m then
				createBobber(source, false)
			end
		end
	end
end)

function drawLine()
	for i,v in pairs(lines) do
		if v then
			if isElementStreamedIn(i) then
				local p = bobbers[i].position
				local m = fishingSticks[i].matrix:transformPosition(Vector3(0.124, 0.034, 1.29))
				dxDrawLine3D(p.x, p.y, p.z, m.x, m.y, m.z, tocolor(0,0,255,200), 0.5)
			end
		end
	end
end
addEventHandler("onClientRender", root, drawLine)

Thanks for the quick answer but the problem lies here. As i said, it works perfectly fine with localPlayer but when i try it with other players on the client side, it just simply doesn't work.

I don't know if i'm an idiot or it's a bug.

 

EDIT: This is a piece of the script, i deleted some parts because it's private

Try it on server side. If the matrix works then I'll help you out to make a server side based script.

I've figured out in the end. Here's the solution:

Since you can't pass matrixs with setElementData (just trust me with that) you have to split the matrix into a table and then do the setElementData part.

So the scripts now looks like this:
 

setElementData(localPlayer, "bobber:create", true)
setElementData(localPlayer, "bobber:pos", {localPlayer.matrix.position.x, localPlayer.matrix.position.y, localPlayer.matrix.position.z, localPlayer.matrix.rotation.x, localPlayer.matrix.rotation.y, localPlayer.matrix.rotation.z})

 

and then at the onClientElementDataChange side of things you have to do this:

local mat = getElementData(player, "bobber:pos")
local matrix = Matrix(Vector3(mat[1], mat[2], mat[3]), Vector3(mat[4], mat[5], mat[6]))

That's all, and some other minor fixes and tweaks solved my problem.

 

You can lock the post know and thanks for the advices.
