Hello, I'm creating a flashing light bar and i'm getting a lot of different error messages, can someone tell me what's wrong with this code?

x = 1
while x < 5 do
all = colors.combine(colors.magenta , colors.cyan , colors.light-grey , colors.purple , colors.orange , colors.lightBlue , colors.yellow , colors.pink)
rs.setBundledOutput("back", colors.magenta)
sleep(0.5)
rs.setBundledOutput("back", rs.getBundledOutput("back") - colors.magenta)
rs.setBundledOutput("back", colors.cyan)
sleep(0.5)
rs.setBundledOutput("back", rs.getBundledOutput("back") - colors.cyan)
rs.setBundledOutput("back", colors.light-grey)
sleep(0.5)
rs.setBundledOutput("back", rs.getBundledOutput("back") - colors.light-grey)
rs.setBundledOutput("back", colors.purple)
sleep(0.5)
rs.setBundledOutput("back", rs.getBundledOutput("back") - colors.purple)
rs.setBundledOutput("back", colors.orange)
sleep(0.5)
rs.setBundledOutput("back", rs.getBundledOutput("back") - colors.orange)
rs.setBundledOutput("back", colors.lightBlue)
sleep(0.5)
rs.setBundledOutput("back", rs.getBundledOutput("back") - colors.lightBlue)
rs.setBundledOutput("back", all)
sleep(1)
rs.setBundledOutput("back", 0)
rs.setBundledOutput("back", all)
sleep(1)
rs.setBundledOutput("back", 0)
sleep(1)
end

Also can someone tell me how to continue this loop without the computer crashing? Thanks

you never increment x, so it is always 0, and therefore will always be less than 5.

add:
x = x + 1

before the end statement

light-grey is not a color (in the colors api), lightGray is. Change that and it may work.

This should work:


local all = colors.combine(colors.magenta , colors.cyan , colors.lightGray , colors.purple , colors.orange , colors.lightBlue , colors.yellow , colors.pink)

for i = 1, 5 do
  rs.setBundledOutput("back", colors.magenta)
  sleep(0.5)
  rs.setBundledOutput("back", colors.cyan)
  sleep(0.5)
  rs.setBundledOutput("back", colors.lightGray)
  sleep(0.5)
  rs.setBundledOutput("back", colors.purple)
  sleep(0.5)
  rs.setBundledOutput("back", colors.orange)
  sleep(0.5)
  rs.setBundledOutput("back", colors.lightBlue)
  sleep(0.5)
  rs.setBundledOutput("back", all)
  sleep(1)
  rs.setBundledOutput("back", 0)
  -- you should add a sleep here, cause it won't do anything like this
  rs.setBundledOutput("back", all)
  sleep(1)
  rs.setBundledOutput("back", 0)
  sleep(1)
end

Use a while loop:


local all = colors.combine(colors.magenta , colors.cyan , colors.lightGray , colors.purple , colors.orange , colors.lightBlue , colors.yellow , colors.pink)

while true do
  rs.setBundledOutput("back", colors.magenta)
  sleep(0.5)
  rs.setBundledOutput("back", colors.cyan)
  sleep(0.5)
  rs.setBundledOutput("back", colors.lightGray)
  sleep(0.5)
  rs.setBundledOutput("back", colors.purple)
  sleep(0.5)
  rs.setBundledOutput("back", colors.orange)
  sleep(0.5)
  rs.setBundledOutput("back", colors.lightBlue)
  sleep(0.5)
  rs.setBundledOutput("back", all)
  sleep(1)
  rs.setBundledOutput("back", 0)
  -- you should add a sleep here, cause it won't do anything like this
  rs.setBundledOutput("back", all)
  sleep(1)
  rs.setBundledOutput("back", 0)
  sleep(1)
end
