How can I use the mob farm shown in the video for Minecraft 1.1.6. Convert for Java so that it also works in the Bedrock edition?

Here is the video where the construction of the bully farm is shown.

How could I redesign the design to work for the Bedrock edition on PS4 and not just for Java?

RedStone works differently with the bedrock edition, the best thing is to look directly for tutorials for the Bedrock edition

If there's only another clock on the redstone circuit, the problem would not be the problem.

I don't know the exact differences a hundred percent, but if you replace the clock it should work, provided that you have no mob limitation or the like programmed into the ps4 edition, it is best to test it in creative mode

In the Bedrock Edition, mobs despawn very badly, for example in caves.
