[1.7.10] Gravity effect

[Cerandior]

I want to be able to create the effect of a low gravity on minecraft. I think the effect of the gravity on minecraft is created by the player always moving with a certain speed in the negative Y direction. At least i think so. If i change the speed with which the player moves in this direction it will create the effect of a low gravity. I think this can be done using a event but i dont know which one is responsible for this. Maybe this can be done without an event but that was my first thought.

When do you want to do this? (when wearing armor, holding item, next to the chicken, next to your mob...)...

When wearing a part of an armor.

When wearing a part of an armor.

Then there's tick method which is called every tick when armor is worn. It is called something like onArmorTick. Do player.motionY manipulations there...
