BCU Attack Animation Converter

Welcome to BCU Attack Animation Converter

This will convert and generate frames to counter the infinite (-1) loop settings on attack animation of the unit. It will slightly increase the file size of the attack animation.

Upload and Read .txt File Kindly upload maanim_attack.txt from your BCU Animations Folder. This will fix and create a fake animations (generate) with animations who have -1 in their animations, it means loop which crashes on application for Battle Cats Game.
