Vector Math

Warning

This API is deprecated since V5.1 and removed in V6 products

Use Vector3 and EulerAngles classes

print(vector.Length(100, 100, 100))
print(vector.Add({0, 0, 0}, {100, 100, 100}))
print(vector.Add({0, 0, 0}, 100))
print(vector.Distance(0, 0, 0, 100, 100, 100))
print(vector.Distance({0, 0, 0 }, {100, 100, 100}))

local function OnDrawESP(builder)
    local ent = builder:GetEntity()
    local localply = entities.GetLocalPlayer()

    builder:AddTextTop("Distance: " .. vector.Distance({ent:GetAbsOrigin()}, {localply:GetAbsOrigin()}))
end

Chat Message Replacement

callbacks.Register("SendStringCmd", function(cmd)
    -- replace "no" with "yes"
    if string.find(cmd:Get(), "say \"no\"") == 1 then
        cmd:Set("say \"yes\"")
    end
end)
