I read through many forum posts, but none seem to explain my issue. So whenever I try to use the paint bucket tool, it doesnt work when I click. I tried to fill the gaps but that didnt work either. I restarted my adobe animate, again no help. I hope I can find answers here.
open a new fla and start a new as3 project
save to a desktop directory
select the rectangle tool
draw a rectangle on stage
select the paint bucket tool and select a fill color
click the on-stage rectangle
Make sure your artwork (assuming you created it using Animate vector tools) does not have any gaps. Also, you may have used Object Drawing mode when the strokes or shapes were drawn. If so, even if they are overlapping, they are separate objects and therefore not a contained shape that could be filled. You can select them all and break them apart or go to Modify > Combine Objects > Union and then use the Fill Bucket.
Also worth nothing the Fill Bucket has sub-selection setings to close small, medium, large gaps which could also be your issue.
