Panicbar
This is a highly customizeable mod for letting players not be able to do "use" action to place blocks, you can see the config files for even more detailed explanations but here are some basic explanations this mod fully allows you to change where the bar appears, how far away from the player does get "panicked", damage and health multipliers that also effects user's "panicking status" (this is not an effect by minecraft standarts just a term for sources that effect player's panic bar)
This means mobs like zombie will panic you 1x and mobs like warden will make you panic 25x due to wardens having 25 as much health compared to a zombie
This also means when you get damaged by a zombie you'll panic bar will go up a little tiny bit compared to a sonic blast which almost fills it up completely if you don't have adequate armour.
You can decrease the panicking by either just waiting or eating something more saturation and absorption points that the food gives it will reduce your panicking more.
With the default config mobs that actively trying to path towards you that are also hostile and within 25 blocks will make it so your panicking bar increases.
For modpack developers
you can configurate the mod in game with "Configured" mod and you don't need to reload the game or the world to take in effect, I'm not sure about the server side part of the mod as I've never had a chance to test in a server but when used in an server it should get the server's config and apply it to everyone. So just edit the server config.
