[REL] DX-Notification Script

[AGENT_STEELMEAT]

Hey all,

I made a simple DX notification script for my gamemode (JohnMode) and I figured I might as well release it since it took 15 minutes to write. Here it is:

  
-- 
--  DX NOTIFICATIONS 
-- 
local notificationQueue = {} 
local drawNotifications 
  
function createNotification(id, message, x, y, width, height, font, scale, textColor, bgColor, showTicks) 
    if notificationQueue[id] then 
        destroyNotification(id) 
    end 
     
    if type(message) ~= "string" or type(x) ~= "number" or type(y) ~= "number" or type(width) ~= "number" or type(height) ~= "number" then 
        return false 
    end 
     
    if type(font) ~= "string" then 
        font = --[[ TODO: Define the a default font! ]] 
    end 
    if type(scale) ~= "number" then 
        scale = --[[ TODO: Define a default scale! ]] 
    end 
    if type(textColor) ~= "table" then 
        textColor = --[[ TODO: Define a default color (in format {r, g, b}) ! ]] 
    end 
    if type(bgColor) ~= "table" then 
        bgColor = --[[ TODO: Define a default background color (in format {r, g, b})! ]] 
    end 
    if not showTicks then 
        showTicks = --[[ TODO: Define a default show time (in miliseconds)! ]] 
    end 
     
    local newNotification = {} 
    newNotification.message = message 
    newNotification.x = x 
    newNotification.y = y 
    newNotification.width = width 
    newNotification.height = height 
    newNotification.font = font 
    newNotification.scale = scale 
    newNotification.textColor = textColor 
    newNotification.bgColor = bgColor 
    newNotification.showTicks = showTicks 
    newNotification.shownTicks = 0 
    newNotification.lastAlpha = 0 
     
    if #notificationQueue == 0 then 
        addEventHandler("onClientRender", root, drawNotifications) 
    end 
    notificationQueue[id] = newNotification 
end 
  
function destroyNotification(id) 
    if notificationQueue[id] then 
        notificationQueue[id] = nil 
     
        if #notificationQueue == 0 then 
            removeEventHandler("onClientRender", root, drawNotifications) 
        end 
    end 
end 
  
--[[local]] function drawNotifications() 
    --[[if not isLocalPlayerLoggedIn(localPlayer) then 
        return 
    end]] 
     
    for id, notification in pairs(notificationQueue) do 
        local shownTicks, lastAlpha = notification.shownTicks, notification.lastAlpha 
        local bgColor, textColor = notification.bgColor, notification.textColor 
         
        -- If the nofication is still new or fading in 
        if shownTicks == 0 then 
            if lastAlpha < 200 then 
                lastAlpha = lastAlpha + 6 
                if lastAlpha > 200 then 
                    lastAlpha = 200 
                end 
                 
                bgColor[4] = lastAlpha 
                textColor[4] = lastAlpha 
                notification.lastAlpha = lastAlpha 
            else 
                notification.firstTick = getTickCount() 
                notification.shownTicks = 1 
            end 
        elseif shownTicks >= notification.showTicks then -- Fade out or delete old notifications 
            if lastAlpha > 0 then 
                lastAlpha = lastAlpha - 6 
                if lastAlpha < 0 then 
                    lastAlpha = 0 
                end 
                 
                notification.lastAlpha = lastAlpha 
                bgColor[4] = lastAlpha 
                textColor[4] = lastAlpha 
            else 
                destroyNotification(id) 
            end 
        else -- Buisness as usual 
            notification.shownTicks = getTickCount() - notification.firstTick 
        end 
         
        dxDrawRectangle(notification.x, notification.y, notification.width, notification.height, tocolor(unpack(bgColor))) 
        dxDrawText(notification.message, notification.x, notification.y, notification.x + notification.width, notification.y + notification.height, tocolor(unpack(textColor)), notification.scale, notification.font, "center", "center") 
    end 
end 
  

Caveats:

- THE SCRIPT WILL NOT WORK PROPERLY IN ITS CURRENT FORM! You need to define your own default variables in the script - this is done to prevent everyone from having the same style notifications.

- This script does not support dx-fonts. If you want that functionality, implement it yourself (it's not hard)!

- This script does not magically ensure that the width of the text is less than the width of the box - that is up to you. You could easily implement an auto-size feature, however.

- It's client-side only (I really shouldn't have to mention this, but you never know).

Cheers and titties.
