This is my code. Why it no work?

craftingTable.removeRecipe(item:ars_nouveau:novice_spell_book.withTag({mode: 0 as int, spells: ",projectile,touch,self,break,harm" as string}));

var novice_book = item:ars_nouveau:novice_spell_book.withTag({mode: 0 as int, spells: ",projectile,touch,self,break,harm" as string});
var book = item:minecraft:book;
var pure_crystal = item:elementalcraft:purecrystal;
var water_crystal = item:elementalcraft:watercrystal;
var air = item:minecraft:air * 0;

recipetype:astralsorcery:simple_altar("novice_book", novice_book, 200, 200, [
air, pure_crystal, air,
water_crystal, book, water_crystal,
air, pure_crystal, air
]);

:(

try just "recipetype:astralsorcery:altar" - that's how the recipe serializer is called.

so would it be

"recipetype:astralsorcery:altar"("novice_book", novice_book, 200, 200, [

Assuming you're using a version for Minecraft 1.12....

What do the logs say?

sorry its in 1.16 i dumped allrecipe types and all it comes up with is simple_alter. Im using crafttweaker

Why not use a vanilla datapack? There's no explicit CT support added in the 1.16 alpha release at this time due to datapack support being present.

im trying to avoid datapacks if possible

That's the available option at the moment. Crafting recipes in Astral Sorcery in 1.16 are fully manageable via datapacks at present.

Is there a crafting involvement that requires CT versus a datapack for Astral Sorcery going on?

recipetype:astralsorcery:simple_altar("novice_book", novice_book, 200, 200, [

this is the bit that i cant get working, apparently it's not teh simple alter

Yes. The CT integration that leveraged that in 1.12 isn't present in 1.16. Again, a datapack solves this.

Please lookup how to add/remove recipes from recipetypes on the CT documentation.
In this manner, recipes can be added with the same syntax as AS' json recipes.

That said, we're not a CraftTweaker helpdesk. If you have further questions on how to use CraftTweaker, ask on their end.

that recipe id thingy is wrong, i tried it but it didn't work
