Currently we rely on some undefined behavior when Object->cast_to() gets
called with a Null pointer. This used to work fine with GCC < 6 but
newer versions of GCC remove all codepaths in which the this pointer is
Null. However, the non-static cast_to() was supposed to be null safe.
This patch makes cast_to() Null safe and removes the now redundant Null
checks where they existed.
It is explained in this article: https://www.viva64.com/en/b/0226/
GDScript was restricted to parse only scripts beginning with __res://__ or __user://__ to avoid templates from being parsed. I've made that a bit less inclusive by allowing scripts with an empty path to be parsed too, which doesn't conflict and is needed for this to work.
Also I've removed the `this` variable of the generated script and made the relevant object to be the one the script instance refers to, so you can use `self` instead.
Now, with the shorter 3.0-style syntax, you can write things like: `self.position.x + 10`
Closes#9500.
Templates will be loaded from .godot/script_templates
For now they're disabled for GDNative.
Ideas for further improvements:
- Add a "Save as Template" option to the script editor, as it can normally only save to res://
- Support more placeholders / custom placeholders
Replaces the `extends` keyword with `is` in the context of testing for type compatibility.
`extends` is still used for declaring class inheritance.
Example:
```gdscript
extends Node2D
func _input(ev):
if ev is InputEventKey:
print("yay, key event")
```
The very first Godot version (when it was open sourced) had "MultiScript" which lets you use multiple scripts on one object.
With the addition of mulitple new scripting languages (VisualScript, soon C# and GDNative) it can be of use to combine scripts rather than delegating (with huge maintainance cost) or creating child nodes
which could impact performance.
I used the code from 0b806ee as the base and made it work with the current master.
I can show you the code
Pretty, with proper whitespace
Tell me, coder, now when did
You last write readable code?
I can open your eyes
Make you see your bad indent
Force you to respect the style
The core devs agreed upon
A whole new world
A new fantastic code format
A de facto standard
With some sugar
Enforced with clang-format
A whole new world
A dazzling style we all dreamed of
And when we read it through
It's crystal clear
That now we're in a whole new world of code
-Changed SectionedPropertyEditor to support this
-Renamed Globals singleton to GlobalConfig, makes more sense.
-Changed the logic behind persisten global settings, instead of the persist checkbox, a revert button is now available
That year should bring the long-awaited OpenGL ES 3.0 compatible renderer
with state-of-the-art rendering techniques tuned to work as low as middle
end handheld devices - without compromising with the possibilities given
for higher end desktop games of course. Great times ahead for the Godot
community and the gamers that will play our games!
-Block switches to 2d/3d editor if editing visual script
-Added cast node in flow control
-Added ability to do RPC in visual script
-Comment nodes
-Fix bug with inverted cable in connecting backwards
-Copy and paste nodes, including from different scripts
With this, visual script is almost done (missing registering custom nodes from addon).
All this is probably pretty broken, too and needs a lot of testing.
