replace part of string lua

To replace a part of a string in Lua, you can use the string.gsub function. The gsub function stands for "global substitution" and allows you to replace all occurrences of a pattern in a string with a specified replacement.

Here are the steps to replace a part of a string in Lua:

1. Define the original string: Start by defining the original string that you want to modify. For example, let's say we have the string "Hello, World!".

2. Call the gsub function: Use the gsub function to perform the replacement. Pass the original string as the first argument, the pattern you want to replace as the second argument, and the replacement string as the third argument. For example, to replace the word "Hello" with "Hi" in the string "Hello, World!", you would use the following code:

lua local originalString = "Hello, World!" local pattern = "Hello" local replacement = "Hi" local modifiedString = string.gsub(originalString, pattern, replacement)

The gsub function returns the modified string as the result.

1. Print the modified string: Finally, you can print the modified string to verify that the replacement was successful. For example:

lua print(modifiedString)

This would output "Hi, World!".

By following these steps, you can replace a part of a string in Lua using the gsub function.
