Hi I want a /showhp command to see the life force and armor of others, I show in the picture what it should look like, I just don't know how to start her, someone's idea?

Hello.

What exactly you wanna do? If it's only show someone else's life and armor, you can create a server-side command and use these following functions:

• getPlayerFromName
• getElementHealth
• getPedArmor
• outputChatBox

if I type /showhp then which player is close to me, it shows the hp on the player as shown in the picture above, in stripes.

I have made an example for you. If you aren't able to understand the code below, I'd suggest you to study Lua and MTA: SA Scripting. There are good topics here, on the forums.

Here are some of them: (by MTA Staff BOT, on our Discord server)

Client-side:

-- Client-side
local screen = Vector2(guiGetScreenSize()) -- Get the client's screen resolution
local barWidth, barHeight = 200, 20 -- Just setting up the health/armor bar width/height
local playerTarget = false -- A variable to set the target player

local function render()
    if playerTarget and isElement(playerTarget) then -- Check if it's a valid player, because once the player leaves the server, it won't be valid anymore
        -- Health
        local health = getElementHealth(playerTarget) -- Get the player's health
        local healthX, healthY = screen.x / 2 - barWidth / 2, screen.y - 80

        dxDrawRectangle(healthX, healthY, (health / 100) * barWidth, barHeight, tocolor(255, 0, 0, 255), false)

        -- Armor
        local armor = getPedArmor(playerTarget) -- Get the player's armor
        if armor > 0 then
            local armorX, armorY = screen.x / 2 - barWidth / 2, healthY + (barHeight + 5)
            dxDrawRectangle(armorX, armorY, barWidth, barHeight, tocolor(20, 21, 22, 255), false)
            dxDrawRectangle(armorX, armorY, (armor / 100) * barWidth, barHeight, tocolor(0, 0, 255, 255), false)
        end
    end
end

-- Add the event on client-side, and we pass `true`, because it will be triggered remotely (by the server-side)
-- It's the same name as in triggerClientEvent function (server-side)
addEvent("hp:show", true)
addEventHandler("hp:show", localPlayer, function(target)
    playerTarget = target -- target is coming from the server-side, so let's save it now, on the client-side, assigning to playerTarget variable
    
    -- Here we are removing and adding the event to render things on the screen
    -- removeEventHandler is not really necessary here, but you can do logics to get this working the way you prefer
    removeEventHandler("onClientRender", root, render)
    addEventHandler("onClientRender", root, render)
end)

 

Server-side:

addCommandHandler("showhp", function(player, command, ...)

    if #args == 0 then -- Just checking if there are arguments - /showhp andr0xy - "andr0xy" is an argument
        return false
    end

    local target = getPlayerFromName(args[1]) -- Here we get the player element, from the nickname
    if not target or not isElement(target) then -- Check if it's a valid player
        return false
    end

    local px, py, pz = getElementPosition(player) -- Get my position (who used the command)
    local tx, ty, tz = getElementPosition(target) -- Get the target's position
    local distance = getDistanceBetweenPoints3D(px, py, pz, tx, ty, tz) -- Calculate the distance between them
    if distance > 5 then -- If both of you are too far, then it will not be executed. 5 meters I'd consider a good distance to check
        return false
    end

    triggerClientEvent(player, "hp:show", player, target) -- If everything is OK, so let's send the info to the client-side
