**Christmas and New Year are a time for gifts.** I have been using Defold for many years, and during this time I collected many useful things: examples, code pieces, small libraries, and solutions that I use in my games. This December, I want to **share them and give something to the community**. I want to share my experience. I hope this will be **useful and interesting**. I prepared **14 gifts**. This is an **Advent calendar**. Every day, I will share **something new** 🎁 DAY 1.(defold-go-position-setter) Fast way to set positions for thousand objects.
