Inventory Weight

[Hellfire Dragon]

I need a script that will give each item in the player's inventory a set weight. The play can't pick up items if they are over the limit. How much the player can carry is based off their total STR stat.
I need this to be compatiable with Blizz ABS, picking items up on the map

Couldn't find this anywhere, i searches

[G_G]

Well I'll need some sort of equation on how to make the strength.

Max Amount of Weigth = average party str * 2

or something like that.

[Hellfire Dragon]

I only only want the leader's strenght stat, since I only have 1 person in the party most of time, if that makes it easier

[G_G]

Okay so if the strength is 20 the max weight is 20?

This easiest method will be name-tagging, or checking each Item's name for "\w[<v>]" and setting weight to V.

Also, you'll only want to do checking when gain_item, gain_weapon, gain_armor, lose_item, lose_weapon, or lose_armor is called.

*makes a version*

EDIT:

Something like this should work, but you'll have to do some fiddling to get it to *really* work with BlizzABS/DBS (ie making items stay on the ground if they're too heavy to pick up, etc, and making an improved items menu, etc):

To give an item weight, simply add "\w[<weight>]" in its name in the editor.
To change the number of strength it takes to increase maximum weight by 1, change either $game_system.wcw_weighted_factor (in-game) or the default value in the script (search for @wcw_weighted_factor =).
To activate/deactivate the system, use $game_system.wcw_weighted_active = <true/false>.

Either that or a case-when configuration method.

Nice Lf ty, so if I wanted to display the inventory's total weight, what could I add to a scene?

To the window where you want to add it:

self.contents.draw_text(<x>, <y>, <w>, <h>, "Total Weight: #{$game_party.wcw_weighted_total_weight}")

EDIT:
Here's some of the useful APIs for my script:

- To get an the weight of an item, weapon, or armor, just use

<object>.wcw_weighted_weight

If it returns -1, then it's not "weighted," which means that no weight is set in the database. Use this how you want to; I made it -1 so it differentiates unset objects from objects weighing 0 (both act as if they weigh nothing, though).

- To get the maximum amount of weight an actor can carry, use

<actor>.wcw_weighted_max_weight

- The current weight of the inventory is stored in

$game_party.wcw_weighted_total_weight

Also, there are two bugs in my script that need to be fixed (I don't have time right now): First, changing the lead actor of the party will cause bugs with the weight (he'll be able to hold too many objects). Handling for this needs to be added to the corresponding code. Second, if the lead actor's strength is reduced, the same problem occurs. This will also need a bit of tinkering (you'll have to open a scene to remove items until the weight is small enough, or something like that).

Okay, thanks Lf
