I have searched and read the tutotrials and the codes Github has given me and Im still confused.

I need some clarification on several things:
*The 'Use' Tab and how it works
*Flags
*Conversation with NPCs
*Javascript and how to use them
*Using Github

the 'flags' are just Boolean VARIABLES:

Attribute VARIABLE examples:

// create ("tv")
tv.switchedon = true
// or:
tv.switchedon = false

// create ("orc")
orc.dead = false
// or:
orc.dead = true

room.visited = false
// or:
room.visited = true

player.flying = false
// or:
player.flying = true

player.poisoned = false
// or:
player.poisoned = true

to do these in the GUI/Editor:

add new script -> 'variables' section/category -> 'set a variable or attribute' Script -> (see below)

examples:

set variable room.visited = [EXPRESSION] true
// or:
set variable room.visited = [EXPRESSION] false

set variable tv.switchedon = [EXPRESSION] true
// or:
set variable tv.switchedon = [EXPRESSION] false

set variable player.poisoned = [EXPRESSION] true
// or:
set variable player.poisoned = [EXPRESSION] false

set variable orc.dead = [EXPRESSION] true
// or:
set variable orc.dead = [EXPRESSION] false
