Group position not computed on resize events

Group components get computed once when their children are added to the render queue.
On a resize event, or every render which doesn't modifies the render queue, Groups aren't recomputed, thus having their children sometimes overflow the viewport when reducing the screen size.

Invisible textures on Firefox

Firefox doesn't show textures loaded from a source image. Color textures (created from a script) are being rendered.

Generic components (Sprite, Text...)

Move the generic components like Sprite and Text from the client to the library.

Find a way to remove the GUIComposite export in the client-side

Possible solutions:

• Store the TextureWrapper name in the component, instead of the whole wrapper
• Pass the context as a constructor argument (this means that all components will require a context argument, even in the clieint-side)
• (Text components only) Pass the font texture along the font

Resize doesn't work properly since text color has been added

Composite and subcomponent shaders

Move the composite/subcomponent shaders from the client to the library.

Font is not assignable to BitmapFont

The return type of GUIComposite.getFont is Font, however the helpers for generating glyphs from a string are located in the BitmapFont subclass; this breaks JSDoc.

Error when disposing the GUI manager

When an exception is catched inside the public main script, the Instance.dispose method is called and disposes all the underlying renderer managers by calling RendererManager.dispose. However this method is not present in the superclass, nor in the GUIManager class which extends it.

Convert Error functions to ES6 classes

Slow texture loading

When the texture list file contains ~40 entries the loading time is ~1s.

Proposition

Use Promise.all to fetch the textures in parallel.
Some textures can also use deferred loading if they are used later.

Add Vector.isNull()

Returns true if the vector's length is 0, false otherwise. To be applied on all Vector classes.

We can avoid computing the length here and instead check if all components are 0.
