scripting help with actors, skills and items

[Memor-X]

i need some help with making a couple of scripts, my RGSS skills are basic and though i know the logic, i'm not sure of the methods (i would be if the classes was constructed using arrays of classes), anyway, here's what i need to know how to do,

• How to check if an actor knows a skill or not (eg. check to see if Actor 1 knows Skill 547)


• How to check if an actor is inflicted with a certain state (eg. Actor 3 is inflicted with State 14)


• How to add and remove skills like the event command


• How to check if an item is in the inventory


• How to check if every index in an array is True without having to use a loop (cause the array i want to check would have over 500 indexes, something is bound to stuff up if i have a running loop)

Here are the ones I'm pretty sure on, although I didn't test.

1. if $game_actor[1].skills.include?(547)
3.$game_actor[1].learn_skill(547) / $game_actor[1].forget_skill(547)
4. $game_party.item_number(547)

• the include? method of arrays can test if an array contains a value


• same as above


• look at the Game_Actor class for the right method


• look at the Game_Party class

if !array.include?(false) && !array.include?(nil)

or if your array is going to include values other than true, false, and nil

ary.uniq.size == 1 && ary[0] == true

In order: 

$game_party.actors[INDEX].skill_learn?(SKILL_ID)

 
Actor at INDEX learns the skill with SKILL_ID

$game_party.actors[INDEX].state?(STATE_ID)

 
Returns true/false if actor at INDEX is inflicted with the state with STATE_ID

$game_party.actors[INDEX].learn_skill(SKILL_ID)
$game_party.actors[INDEX].forget_skill(SKILL_ID)

 
Actor at INDEX learns/forgets skill with SKILL_ID

$game_party.item_number(ITEM_ID) > 0

 
Returns true/false if party has item in inventory with quantity greater than 0

array.all?

If you are simply checking for all "true" you can simply do that. A block has to be supplied if you are checking conditions with this method.

... I though there was an all? method but when I went looking for it to make sure I couldn't find it.... then I looked at the enumerable module ?*facepalm*
