I have absolutely no experience with advanced programming and JS, but I want to use a mod and its API for some simple customizations. The only thing I want to do is:
1) Add already-existing blocks but alter the texture slightly
2) Add already-existing advanced blocks that have complexities behind them, but all I want to do is copy them and alter their texture slightly
Is it difficult to do this? All I want to do is copy and paste the different blocks and alter their block textures slightly.
