FileCreate
Creates a new file in a directory of a resource. If there already exists a file with the specified name, it is overwritten with an empty file.
Note: The file functions should not be used to implement configuration files. It is encouraged to use the XML functions for this instead.
Syntax
file fileCreate ( string filePath )
Required Arguments
- filePath: The filepath of the file to be created in the following format: ":resourceName/path". 'resourceName' is the name of the resource the file is in, and 'path' is the path from the root directory of the resource to the file.
- For example, if you want to create a file named 'myfile.txt' in the resource 'mapcreator', it can be created from another resource this way: fileCreate(":mapcreator/myfile.txt").
- If the file is in the current resource, only the file path is necessary, e.g. fileCreate("myfile.txt").
file fileCreate ( string filePath [, string accessType = "public" ] )
Required Arguments
- filePath: The filepath of the file to be created in the following format: ":resourceName/path". 'resourceName' is the name of the resource the file is in, and 'path' is the path from the root directory of the resource to the file.
- For example, if you want to create a file named 'myfile.txt' in the resource 'mapcreator', it can be created from another resource this way: fileCreate(":mapcreator/myfile.txt").
- If the file is in the current resource, only the file path is necessary, e.g. fileCreate("myfile.txt").
Optional Arguments
- accessType : This setting determines whether to create a public or private version of the file at filePath.
- "public" will create a file that is shared by all servers.
- "private" will create a file that only the current server is allowed to access.
Returns
If successful, returns a file handle which can be used with other file functions (fileWrite, fileClose...). Returns false if an error occured.
Example
This example creates a text file in the current resource and writes a string to it.
local newFile = fileCreate("test.txt") -- attempt to create a new file
if (newFile) then -- check if the creation succeeded
fileWrite(newFile, "This is a test file!") -- write a text line
fileClose(newFile) -- close the file once you're done with it
end
Notice that you can't simply do fileWrite("test.txt", "File content"). Instead, file functions operate on a file handle, which is a special object representing an open file. fileCreate creates a file, opens it, and returns the resulting handle.
It is also important to remember to close a file after you've finished all your operations on it, especially if you've been writing to the file. If you don't close a file and your resource crashes, all changes to the file may be lost.
