Writing Files in GDScript
Here’s the translation of the Go code to GDScript, with explanations in Markdown format suitable for Hugo:
Writing files in GDScript follows similar patterns to the ones we saw earlier for reading.
extends Node
func _ready():
# To start, here's how to dump a string (or just bytes) into a file.
var content = "hello\nGodot\n"
var file = File.new()
var err = file.open("user://dat1", File.WRITE)
if err == OK:
file.store_string(content)
file.close()
else:
print("Error opening file")
# For more granular writes, open a file for writing.
err = file.open("user://dat2", File.WRITE)
if err == OK:
# It's good practice to close the file when you're done with it.
# In GDScript, we don't have defer, so we'll need to remember to close it manually.
# You can write byte arrays as you'd expect.
var d2 = PoolByteArray([115, 111, 109, 101, 10])
file.store_buffer(d2)
print("wrote %d bytes" % d2.size())
# A store_string is also available.
var n3 = file.store_string("writes\n")
print("wrote %d bytes" % n3)
# GDScript doesn't have a direct equivalent to Sync,
# but file operations are automatically flushed when the file is closed.
# GDScript doesn't have a built-in buffered writer,
# but you can implement your own if needed.
file.close()
else:
print("Error opening file")
# Try running the file-writing code.
# Then check the contents of the written files in the user:// directory.
# In Godot, user:// maps to a user-writable directory that depends on the platform.
# Next we'll look at applying some of the file I/O ideas
# we've just seen to the standard input and output streams.To run this script, you would need to attach it to a Node in a Godot scene. The _ready() function will be called automatically when the scene is loaded.
Note that in GDScript, we use the File class for file operations. The user:// prefix is used to specify a user-writable directory, which is platform-dependent.
GDScript doesn’t have some of the features that Go has, such as defer for resource cleanup or built-in buffered writers. However, it provides similar functionality through its own methods and idioms.
Remember to handle errors appropriately in your actual code, as file operations can fail for various reasons.
