make a sprite running on links

[pyweeker]

Hello, shaders are not supported yet, but i'd like to add this kind of sprite, following the tracks where energy is running as a symbol of electrons ; dont know how to implement it, but could be easy fast good looking effect

i can look after a png for background transparent alpha , with free copyright.

I had something similar implemented. You can find the code in src/gate/graphics/connection_line.rs.

There is a function (system) called draw_data_flow that checks for DataPoints and moves them along a bezier curve (the associated connection line).

The function draw_line_system redraws all connection lines each frame, this is something that I need to change for obvious reasons. I also used that function to draw the dots representing the data/ energy flow.

You could reuse the DataPoint component and add your sprite(s) as child/ children. Then you would need a new system that iterates over all ConnectionLine components and spawns a new DataPoint for each in a fixed time interval (look at the bottom of draw_line_system for some inspiration - maybe you can just use the commented code).

Also make sure to add the draw_data_flow system in src/gate.rs.

I personally found it a little bit distracting but maybe you can come up with a decent visualization :). If you've further questions, feel free to ask.
