npc's Issues

Algorand Dev Portal article has issues fixed in this codebase

First, thank you immensely for the excellent tutorial on Algorand.org, as a web3 (EVM) game developer learning Algorand, it's educational and fun.

I wanted to give a heads up that the tutorial, Simple NPC game interactions using a stateful contract and atomic transfers, has a number of minor mistakes, which are fixed in this repo's code, but haven't been applied to the article yet.

1. Missing definition of is_creator (line 10) of contract.py

2. Bytes("damage") should be Bytes("injure") on Line 40 of contract.py

3. Makefile references to $(ALGO_(DATA) and $(ALGO__DATA) (should be $(ALGO_DATA))

4. Makefiles also require tabs, not spaces (This may not be fixable in the article, depending on their CMS)

5. goal node start -d $(ALGO_PVTNET_DATA) is a useful command to add after the private node install. (I'm a complete AlgoN00b!)

6. creatorAddress and differentAddress needing some figuring out. goal account new was useful for creating the differentAddress.
   It may be helpful to give commands to create and fund a second account:

   goal account new
   goal account list
   goal clerk send -a 200000 -f $CREATOR_ACCOUNT -t $NEW_ACCOUNT 
   

   I hope this helps! Thanks again!

Issue in Environment variables setup

I created the test net and started it.
checked the status using goal status and make status
All looks good.
The
wallet gets created under
~/algorand/algo-builder/infrastructure/node_data/Primary Not PrimaryNode like the example says

But when i deploy i get the following error

➜  npc make deploy
goal app create --creator IFM4HAAKD3Z7GAOKWQ4SZILY6AMOKHDSW6RWR4MS7MPIC25F4V2E2XDBDE \
                --approval-prog ./build/george_interact.teal \
    --clear-prog ./build/clear_state.teal \
                --local-byteslices 0 \
                --local-ints 0 \
                --global-byteslices 1 \
                --global-ints 1 -d "~/algorand/algo-builder/infrastructure/node_data"
No wallets found. Create a new wallet with `goal wallet new [wallet name]` 

The wallets exist under the Primary Directory
which i tried adding to the path and it complained about not finding algod.
Since this is a beginer example this needs to be fixed and made easy to implement.
