Hello! This is simple, so I’ll get straight to the point.
I wanted to create 3 textboxes, which allow players to input an RGB value to change the colour of some items. This is my current script.
script.Parent.MouseButton1Down:Connect(function()
local Red = script.Parent.Parent.Red.ValueTaker.Text
local Green = script.Parent.Parent.Green.ValueTaker.Text
local Blue = script.Parent.Parent.Blue.ValueTaker.Text
if tonumber(Red) and tonumber(Green) and tonumber(Blue) then
local R = tonumber(Red)
local G = tonumber(Green)
local B = tonumber(Blue)
if 0 >= R <= 255 and 0 >= G <= 255 and 0 >= B <= 255 then
print(R,G,B)
end
end
end)
Upon running, this error persists. 10:19:11.810 - Players.Loggkat.PlayerGui.ScreenGui.TextButton.LocalScript:9: attempt to compare boolean and number
Not sure if it would help, but here is the hierarchy of the GUI, as the problem seems to be based on the logic of transforming the string to a number.
Probably some small stupid mistake I’m doing, but I just can’t see what I’m doing wrong.
Thanks in advance!
if 0 >= R and R <= 255 and 0 >= G and G <= 255 and 0 >= B and B <= 255 then
print(R,G,B)
end
If statements in Lua don’t work with compound inequalities. What it does in your code is get a bool from one part of the comparison and it’s comparing a bool (if the comparison is true or false) to a number, which errors.
Can I recommend that you just clamp the values instead?
local Red, Green, Blue = -50, 50, 285
R, G, B = tonumber(Red) or 0, tonumber(Green) or 0, tonumber(Blue) or 0
for i, v in next, {R = R, G = G, B = B} do
getfenv(0)[i] = math.clamp(v, 0, 255)
end
table.foreach({R, G, B}, print) --> Prints 0, 50, 255
In your case:
script.Parent.MouseButton1Down:Connect(function()
local Red = script.Parent.Parent.Red.ValueTaker.Text
local Green = script.Parent.Parent.Green.ValueTaker.Text
local Blue = script.Parent.Parent.Blue.ValueTaker.Text
if tonumber(Red) and tonumber(Green) and tonumber(Blue) then
local R = math.clamp(tonumber(Red), 0, 255)
local G = math.clamp(tonumber(Green), 0, 255)
local B = math.clamp(tonumber(Blue), 0, 255)
print(R, G, B)
end
end)
