Hello, I'm new in modding and I wanted to make it so that when putting on armor, the effect of potions was given, but all the lessons are for older versions of Minecraft and they do not work on 1.15.1
Could you help me, thanks in advance.

(I do not know English very well and therefore translated via Google Translate. Sorry If there are grammatical errors)

You could listen to the LivingEquipmentChangeEvent event, check if the equipped armor is of a specific type, and if so apply the effect to the entity. Then you would also have to detect if the entity unequipped the armor, and if so remove the effect.

 

Alternatively, if the armor in question is your own mods custom armor, you could override onArmorTick() and periodically reapply the potion effect.

 

Here is a recent post (although for 1.16) discussing a similar issue: link

I used LivingEquipmentChangeEvent and no errors were found in the code, but for some reason, when I put on the armor, minecraft crashes.

I would advise against copying code you don't fully understand, since it will most likely introduce bugs. First of all, remove 'value = Dist.CLIENT', since you cannot add potion effects on the client (I believe this was also discussed in the thread I linked).

 

Second, have you tried debugging / checking the logs to find out where and why it crashes? It is very hard for me to stare at a PNG of code trying to detect what is wrong.
