When you press the flag it asks you how many petals and what the crafting chance is (give it the percent but without the percent sign). Once you give it the numbers press the craft button and it will craft it. This is what I spent the past week ̶m̶a̶k̶i̶n̶g̶ fixing. It was decent but the animation was very very bad and I had only spent about 2 hours on it prior to fixing it. It had little under 100 blocks but now it has 400 blocks and a better animation! (before it was just 5 legendary wings spinning. It was only legendary wings) The animation isn't 100% finished yet because the end is slightly strange and the spinning isn't quite right but it seems fine and looks alright to me. Might not be 100% accurate but with my tests the average from crafting 5 is very close to 0.036 which as a percent is 3.6% or the same chance I gave it. @-Rex- for text engine (font Ubuntu) modified by me. @FourPIayerChess for the input idea (using ask blocks)
