Can you add potion effects to custom items?

I am new to plugin making and recently I have been playing around with custom items and custom crafting recipes. I want to make a plugin that if the player has one particular custom item in hand, it gives them a potion effect, such as invisibility. I have seen plugins like this on some servers I go on and was wondering how to do this myself.

 

@Knight_of_Ni Easier for me to say then done, but I do believe there is an event out there that allows you to run stuff when a player equips an item. You could then check the item meta of the equipped item, and if it is the custom item then give the player a potion effect.

 

If im understanding you correctly this is what you should do;
Create/use a PlayerInteractEvent
Check the action
Probably should check if its ItemMeta is equal to what the custom item should be. (Like a custom lore / display name?)
Then give them the potion effect.

 

I got it to work. thx for the help : )
