Hello, i'm trying to create a function create3DText, to show in-game 3D text, which was created with dxDrawText.
Although function works, but i have a strange problem and i don't know how to solve it.
Here are my client-side script:
local TextLabels = { }
local i = 0
function create3DText(text, color, font, scale, x, y, z, dist, dimension, hex)
if not dimension then dimension = 0 end
i = i + 1
local elm = createElement('base')
setElementPosition(elm, x, y, z)
setElementDimension(elm, dimension)
TextLabels[i] = elm
local elmData = { }
elmData['text'] = text
elmData['color'] = color
elmData['font'] = font
elmData['scale'] = scale
elmData['dist'] = dist
elmData['hex'] = hex
setElementData(elm, 'text.elm.Data', elmData)
return i
end
function destroy3DText(labelID)
if not labelID or not TextLabels[labelID] then return end
table.remove(TextLabels, labelID)
setElementData(TextLabels[labelID], 'text.elm.Data', false)
if isElement(TextLabels[labelID]) then destroyElement(TextLabels[labelID]) end
end
function showLabels()
for i, label in pairs(TextLabels) do
if isElement(label) then
local elmData = getElementData(label, 'text.elm.Data')
if isElement(elmData['attach']) then
local posX, posY, posZ = getElementPosition(elmData['attach'])
setElementPosition(label, posX, posY, posZ)
end
create3DText_(label, elmData['text'], elmData['color'], elmData['font'], elmData['scale'], elmData['dist'], elmData['hex'], elmData['aX'], elmData['aY'], elmData['aZ'])
else
table.remove(TextLabels, i)
end
end
end
addEventHandler('onClientRender', getRootElement(), showLabels)
function create3DText_(elm, text, color, font, scale, dist, hex, x, y, z)
if not x then x = 0.0 end
if not y then y = 0.0 end
if not z then z = 0.0 end
local mX, mY, mZ = getElementPosition(elm)
local cX, cY, cZ = getCameraMatrix()
if isLineOfSightClear(cX, cY, cZ, mX, mY, mZ, false, false, false, false, false, false, false, elm) then
local distance = getDistanceBetweenPoints3D(cX, cY, cZ, mX, mY, mZ)
if distance <= dist then
local pX, pY = getScreenFromWorldPosition(mX + x, mY + y, mZ + z, 0.06)
if pX then
dxDrawText(text, pX, pY, pX, pY, color, scale, font, 'center', 'center', false, false, false, hex)
end
end
end
end
function attach3DText(labelID, element, x, y, z)
if not element or not labelID then return end
for i, label in pairs(TextLabels) do
if i == labelID then
local elmData = getElementData(label, 'text.elm.Data')
elmData['attach'] = element
elmData['aX'] = x
elmData['aY'] = y
elmData['aZ'] = z
setElementData(label, 'text.elm.Data', elmData)
break
end
end
end
addCommandHandler('say1',
function(cmd, ...)
if isTimer(timer) then
killTimer(timer)
destroy3DText(getElementData(getLocalPlayer(), 'text.elm.attach'))
setElementData(getLocalPlayer(), 'text.elm.attach', false)
end
local ontop = create3DText('* '..getPlayerName(getLocalPlayer())..' '..table.concat({...}, ' '), tocolor(194, 162, 218, 255), 'default-bold', 1.05, 1404.7156,238.8190,19.5547, 20.0, 0, false)
attach3DText(ontop, getLocalPlayer(), 0.0, 0.0, 1.2)
setElementData(getLocalPlayer(), 'text.elm.attach', ontop)
timer = setTimer(function(label)
destroy3DText(label)
setElementData(getLocalPlayer(), 'text.elm.attach', false)
end, 1000 * 10, 1, ontop)
end)
The problem is, with destroying 3D text's. For a test, i written /say1 command.
Example: if i type '/say1 one' - it shows, everything is ok, and after 10 seconds timer destroys it, same as for '/say1 two', '/say1 three'... BUT Dunno why, but after third test, typing '/say1 four' it shows but timer won't destroy it... Also this part from command:
if isTimer(timer) then
killTimer(timer)
destroy3DText(getElementData(getLocalPlayer(), 'text.elm.attach'))
setElementData(getLocalPlayer(), 'text.elm.attach', false)
end
won't destroy it and i dunno why this could be happen.
Any solution would be really appreciated.
