How can you program in a forge mod that the player gets an effect when he wears armour, for example?

I would like that when the player wears a piece of armour from my mod, that he then gets Jump boost, is that possible and if so how?

Jump Boost is a potion effect, it doesn't apply to items.

The correct way to do this is to add your own net.minecraft.world.entity.ai.attributes.Attribute for this (unfortunately for you, Jump Boost doesn't use an Attribute). There is one for horse jumping.

 

The quick and dirty alternate is to subscribe to LivingEquipmentChangeEvent and add/remove the mob effect yourself.

Thanks, Warjort, but my problem is that I don't know how to add/remove an effect and I dont know how the LivingEquipmentChangeEvent works.

For an example look at WitherSkeleton.doHurtTarget()

And events are explained on that same wiki: https://forge.gemwire.uk/wiki/Main_Page

Tanks warjort and now I know how to apply effects to the player and how to check if the player wears armor, but to apply an effect to the player I need to get the player object I saw a Declaration to this but It doesn't work in 1.19. Sorry for so many questions as you see I'm a beginner. And sorry if my english is bad I'm from germany

All LivingEntityEvents have a getEntity()
