Hello,
What's the method that checks if player can take a certain stack? Like, if the player has 35.5 full stacks of dirt in their inventory, they still can take a stack of 32 blocks of dirt, but can't take either a stack of  33 dirt or a stack of any amount of cobblestone.

PlayerInventory#addItemStackToInventory 's javadoc:
"Adds the stack to the first empty slot in the player's inventory. Returns {@code false} if it's not possible to place the entire stack in the inventory."

There's also:

ItemStackHandler.insert(stack, true).isEmpty()

Wait a minute... where can I get Minecraft source with javadoc? I've always used the .jar that is included in Forge MDK decompiled with Fernflower whenever I need to take a look at the game code.

Its in your external resources.

The first one is most of the code, client-extra.jar has a lot of the recipes, blockstates, and such.

Is this Eclipse? Apparently it has a different initial gradle script than IntelliJ - which I am using. I don't have two forge libraries. I only have one which contains the compiled .jar file.
And, yes, I also have client-extra and I use it as well.

External Libraries

Thank you all for trying to point me out where to find the source/recomp library, but I know where would it be, it is just not present in my External Libraries list now, when I work with 1.16.1. The only way I can access it is from file explorer. Maybe some configuration error. Anyway, this thread seems to have deviated much from the topic.

I wrote a function:

public static void giveItemStack(PlayerEntity player, ItemStack stack) {
  if (!player.addItemStackToInventory(stack)) {
    player.dropItem(stack, false);
  }
}

that now works pretty much the same as the /give command, which is exactly what I wanted.

Thanks @Dzuchun for that precious piece of information.
