Hello everyone,
im currently working on a Wallmounted LED 4 connect game (first project with c++ and microcontroller).
The Animations works just fine but i have a problem with the last status which gets overwritten.
(it will just show the last coin and nothing else)
My first idea was to store every step in a vector but that failed horribly due to storage issues (have no clue how to correct save/edit stuff during runtime).
For a better understanding i will attach how my build looks like.
Game logic itself is not needed this will be done by the node server.
Every help/idea to solve this issue is welcome. Thx in advance.
