Hello everyone here, I really need help.
I have rewrote a chat script from a game in order to make it able to wrap lines.
The problem is that the result is different depending on the platform.
-
What do I want to achieve: I am trying to make the text display correctly. The message itself is composed of two TextLabels, the first one is containing the username and the rank, and the second one contains the content of the message:
Well this seem to work perfectly ! It even works on mutiple lines:
And this leads us to the second point, -
But, where is the issue: Well, randomly discovered what caused this, but it appears that the chat is not working properly on some devices. What happens is that the content of the message is cut (letters or even words) at the end. This issue happens when you set the display zoom to 125 % in Windows settings. With a zoom of 100 %, no issues seem to happen. Here is what happens with a zoom of 125 %:
-
What have I tried to fix this: I have tried to do some changes to ensure accuracy in the code, but I am sure that it is not related and that the real problem is located in the Roblox Engine.
Some technical details: the resolution of my monitor is 1920x1080.
Under the hood I have seen that the number of pixels returned by TextService:GetTextBoundsAsync() goes from an integer (with 100% zoom) to a lower float number (with 125% zoom)
Here are some screenshot to compare sizes between Windows zooms:
100% zoom:
125% zoom:
(even the ELO doesn’t display)
Here is a chunk of the faulty code (contains debug prints, that you can match with the screenshots, and yes, I know this is probably not the best code but I’m sticking with this coding technique):
local function showMessage(from : Player, message : string, isTeam : boolean, isDead : boolean, customColor : Color3, plrRank : string, plrColor : BrickColor)
local clonedTemplate = chatElementTemplate:Clone()
local clonedTemplateText = clonedTemplate:WaitForChild("Txt")
print("DEBUG: DispData")
print(from)
print(message)
print(isTeam)
print(isDead)
print(customColor)
print(plrRank)
print(plrColor)
local textBoundsParams = Instance.new("GetTextBoundsParams")
textBoundsParams.Font = clonedTemplateText.FontFace
textBoundsParams.Size = clonedTemplateText.TextSize
textBoundsParams.Width = 0
local textBoundsParams2 = Instance.new("GetTextBoundsParams")
textBoundsParams2.Font = clonedTemplate.FontFace
textBoundsParams2.Size = clonedTemplate.TextSize
textBoundsParams2.Width = 0
clonedTemplate.Name = "ChatText"
if plrRank == nil then
plrRank = "norank"
end
clonedTemplateText.Text = message
if from ~= nil then
local realName = ""
if isTeam then
realName ..= translatorLib.GetTranslationOfKey("ChatUtils.Team") .. " "
end
if plrRank ~= "norank" then
realName ..= translatorLib.GetTranslationOfKey("Roles.String_" .. tostring(plrRank)) .. " "
end
if isDead then
realName ..= translatorLib.GetTranslationOfKey("ChatUtils.Dead") .. " "
else
if plrColor ~= nil then
clonedTemplate.TextColor3 = plrColor.Color
end
end
realName ..= from.Name
clonedTemplate.Text = realName .. ":"
end
textBoundsParams2.Text = clonedTemplate.Text
if customColor ~= nil then
clonedTemplateText.TextColor3 = customColor
end
local positionOffset = 0
if from ~= nil then
positionOffset = textService:GetTextBoundsAsync(textBoundsParams2).X + 5
print("Computed positional offset 1")
print(positionOffset)
end
clonedTemplateText.Position = UDim2.new(0, positionOffset, 0, 0)
textBoundsParams.Text = message
textBoundsParams.Width = (chatScroll.AbsoluteCanvasSize.X - 12) - positionOffset
local computedSize = textService:GetTextBoundsAsync(textBoundsParams)
print("Computed positional offset 2")
print(computedSize)
clonedTemplateText.Size = UDim2.new(0, computedSize.X, 0, computedSize.Y)
clonedTemplate.Size = UDim2.new(clonedTemplate.Size.X.Scale, clonedTemplate.Size.X.Offset, clonedTemplate.Size.Y.Scale, computedSize.Y)
clonedTemplate.Parent = chatScroll
textBoundsParams:Destroy()
textBoundsParams2:Destroy()
print("==================================================")
end
Any help would be greatly appreciated 
, because it’s kind of frustrating to see only 9/10 of your message in chat.
Anyways, good evening !
