Draw text when player enter zone

[maximaler]

Hello!
How I can do when player enter zone then show text and then player leave zone text hide?

I try this
function DrawInfo(pos, txt, clr)
    pos = pos:ToScreen()
    draw.TextShadow( {
        text = txt,
        pos = { pos.x, pos.y },
        font = "FontName",
        color = clr,
        xalign = TEXT_ALIGN_CENTER,
        yalign = TEXT_ALIGN_CENTER,
    }, 2, 255 )
end

MY_ZONE = Vector( 123, 123, 123 )
if LocalPlayer():Team() == TEAM_CITIZEN then
for k,v in pairs(ents.FindInSphere(MY_ZONE, 100)) do
DrawInfo(MY_ZONE, "Warning!", Color(255, 0, 0))
end
end

You need to add if statement inside for loop. If the entity is a localplayer then show text

[mcNuggets]

It needs to be inside a 2d hook.
If you want to draw the warning only if it's a specific entity use GetClass. (dont only check for local players, your weapons are entities too)
ALSO break the loop otherwise it will be drawn x the amount of entities found.

Knowing that you are searching for the player and checking if they are inside, then drawing ...
Put this inside hudpaint ON CLIENT:
MY_ZONE = Vector( 123, 123, 123 )
if LocalPlayer():Team() == TEAM_CITIZEN then
for k,v in pairs(ents.FindInSphere(MY_ZONE, 100)) do
if v == LocalPlayer() then
DrawInfo(MY_ZONE, "Warning!", Color(255, 0, 0))
end
end
end
inside of your HUDPaint.

More efficient way is just grabbing your own position and using Vector/WithinAABox, instead of looping over the entities in that sphere for no good reason what-so-ever

Better way would be using triggers as you can setup outputs to fire when player enters or leaves it.

Honestly I think this is the easiest managed way, especially give StartTouch and EndTouch are functions you can use which are typically what you would need for something like this

if u want do it that way, then your code should look like this

MY_ZONE = Vector( 123, 123, 123 )

local function DrawWarningText()

local plyF = ents.FindInSphere( MY_ZONE, 100 )

for k, v in pairs(plyF) do

if LocalPlayer():Team() == TEAM_CITIZEN then

local pos = MY_ZONE:ToScreen()

    draw.TextShadow( {
        text = "Warning!",
        pos = { pos.x, pos.y },
        font = "FontName",
        color = Color(255, 0, 0),
        xalign = TEXT_ALIGN_CENTER,
        yalign = TEXT_ALIGN_CENTER,
    }, 2, 255 )

end

end

end
hook.Add("DrawOverlay", "DrawWarnings", DrawWarningText)

I really really hope you're not writing code like that, since i had to fix someone's code that did the same shit that for some reason decided to add one extra line for every line making the code readability imposible

It looks awful in code tags. I call it kinda enterprise code. But I agree that sometimes its not lookin' good. Usually I skip some tabs, some not.
