You have season ticket, right?
The dialogue has a call to action function that lets you broadcast on a channel.

but how do I make it so It connects to a vending machine and actually let you buy it with a amount of silver seeds (10)

[PhoenixWander]

Go to channels on the vending machine and make the call to action broadcast channel the same as the Attempt to buy when receiving on channel

Okay. A lot of images here, so…

LENGTH WARNING!!!

ALSO, THE PICTURED USERNAME IS A CHICKEN. THE & IS THE COMB, THE : THE EYES, AND THE > THE BEAK.

Anyways, here goes...

Each of those Dialogue Action devices corresponds to the Vending Machine it sits upon - SILVER to GOLD, GOLD to SILVER, BRONZE to SILVER, SILVER to BRONZE.

So, let’s visit the Shopkeep…

Now, let’s do our Get Rich Quick! Scheme to make sure we can afford his wares…

Our inventory…

Now let’s talk to the Shopkeep…

Let’s buy the first option - SILVER to GOLD.

Awh, no problem-o, Shopkeep!

And the transaction was a success! Now, let’s do something evil…

~Voila~! You have read through this guide and become a trader maker master!

How would I use this method and make it so you need 10 silver seed to buys like 10 dirt blocks and 2 gold for 2 diamond etc

[mutantSackboy4]

Modify the Vending Machine data to show 10 Dynamic Dirt as the output and 10 Silver Seed as the input, or 2 Gold Seed and 2 Dynamic Diamond.
