I want to load a script at runtime. It should be possible for the user to write a script and load this at runtime. The program should then execute a method from this script. Security is not important at this point. So if the user could crash the whole program, it is his/her own problem. It would be great if godot could just evaluate a string with some code and call a method from this afterwards. If this isn't possible, i will implement a small scripting language by myself. I don't need that much functionality. But this would be some work and if Godot can already do this, why not use it?

For those who are interested, i need to write a graph-editor and want to make it extendable. So it should be possible for the user to define own node types, write code to evaluate if the graph is valid, write an extension for export and so on. Some parts of this could could be built with c onfiguration files, but for the evaluation and export part, it would be better to have some kind of scripting language. So having just confoguration files isn't enough in my case.

I do not know for sure, but you may be able to use the Script class (documentation) to load a string containing GDScript code. In theory you'd just need to change the source_code variable and then call the reload function, but I've never used the Script class myself so I do not know for sure.

Hopefully this helps :smile:

Just tried it out with some node which had an empty script already attached.


$someNode.script.source_code="extends Reference\nfunc hw():\n\tprint(\"Hello World\")\n"
$someNode.script.reload(true)
$someNode.hw()

seems to work.
