I have a roleplay server in which there are 6 species to choose from, all with different buffs and debuffs, and one of the species I have cannot swim. When they enter water, they are physically unable to swim upwards and sink to the bottom. Unfortunately I have found no plugins that actually do this (aside from one that physically keeps me out of the water, but that's not what I'm looking for.) Is there by any chance a plugin that can be made that will set my PEX group to not be able to swim upwards? I'm just looking for a plugin that will take away the ability to swim upwards, thanks!
