ive seen someone write that you can use a "changer" to change the string instead of clearing the glasses, what is this so called "changer"?

if i just simply change the string thats on the glasses without clearing, say from "Sparta" to "Imagine" i get something that looks like "$#a&&ne"

so how exactly do i change the string without clearing? i cant find any lines i can use like glasses.changeText

each time you call one of the base methods on a terminal glasses bridge, such as addBox, addGradientBox, addText, (latest 1.6.4 version) addLiquid, (latest 1.6.4 version) addIcon, they return a table of functions that you can use to directly modify the element. You can see a list of all of these functions by doing the following

local bridge = peripheral.wrap("left")
local mainHeading = bridge.addText(10, 10, "<<default text>>", 0xFF0000)
for k,v in pairs(mainHeading) do
  print(k, ' = ', v)
end

If you run the above code you will notice that there'll be a function listed there called setText, this is what you use to change the text of a text element.

Just in case this simple explanation isn't clear enough, example:

local textBox = peripheral.call("left", "addText", 10, 10, "Some text", 0xFF0000)
sleep(10)
textBox.setText(":0 the text has changed!")
