Hi Benjamin,
Merci beaucoup for the fast answer!
Thank you for idea of the drawing list it will help me a lot!
Before I got your message, I already started a new class called ring with a
dictionnary for the midi keys mapping and I writed two render functions.
One for iddle state and the second when an event occurs.
What I want to implement:
I want to keep the ring printed on screen and when an event occur, the
sector concerned would glown shine or I dont know what kind of fancy effect
(here I drawn a blue sector).
I don't know much about pyglet structure, batch or vlist. and I don't know
how to implement it properly. Should I integrate the draw_list into my ring
class? Can I write a function in the sector class who tweak the sector and
I call this function directly on the dictionnary? There is a lot of points
I don't master and I want to write it like KISS. (Keep It Simple and Stupid)
Thank you for your support! I appreciate that :D I sought an active
community to ask questions and learn. here I am
Eelke
