Hi @ams I’d suggest you post a new topic with your question and share the code you have already written. Please read the [guidelines on asking questions](https://discourse.processing.org/t/guidelines-asking-questions/2147/8) and don’t forget to add the `Homework` tag to your post 😉

It’s a little difficult without arrays.

You would need for each particle/ shrapnel  
x1,y1 pair and x2,y2 pair and so on

OR you do it in a for loop and esch iteration represents one shrapnel

Then calculate with increasing radius and angle and cos and sin
