OpenInv Integration with command blocks

[jedijacob2210]

Is there a way to make OpenInv cooperate with command blocks? Eg. Search a player's inventory then execute a command?

Vanilla already has this capability.

If you're looking to chain the command block into another command block you can use /clear with an amount of 0, which outputs the amount of matching items as the success count rather than clearing anything.

If you're looking to conditionally execute a command directly, you can use /execute if entity conditionally dependent on NBT, specifically the Inventory tag. I found several promising results searching "minecraft command block check player inventory" if you're after a relatively preformed command. I'm not confident enough in my understanding of the execute command to write you a sample from scratch.
