Troops width & height

[Dargor]

Hello.

I really need help! :please:
I want to calculate the width and height of a troop and also, if possible, calculate the x and y of this troop. Here's an exemple of what i mean.

The enemies selected in red are making one troop. As i mentioned above, i want to calculate the x,y,width and height of this selection but i have no idea on how to make it.

Help me please! :please:

Where are you doing it from?

At any rate, you can find the screen x and y of a battler in Game_Enemy. You can access them from $game_troops.enemies, which is an array, and the method names are #screen_x and #screen_y.

The height and width are a little trickier. While you can get them from Sprite_Battler from the bitmap property using #height and #width, the only class with access to Sprite_Battler objects is Spriteset_Battle. You'll need add a hook from Game_Enemy to its respective sprite, or to the height and width of that sprite. I'd do this in Spriteset_Battle, when the sprites are created. For example:

@enemy_sprites = []
    for enemy in $game_troop.enemies.reverse
      @enemy_sprites.push(Sprite_Battler.new(@viewport1, enemy))
    end

to:

@enemy_sprites = []
    for enemy in $game_troop.enemies.reverse
     sprite = Sprite_Battler.new(@viewport1, enemy)
      @enemy_sprites.push(sprite)
      enemy.sprite_height = sprite.bitmap.height
      enemy.sprite_width = sprite.bitmap.width
    end

Where sprite_width and sprite_height are accessible attributes you added to Game_Enemy, like so:

attr_accessor :sprite_width
attr_accessor :sprite_height

Now you should have all the data to calculate the corners of the area from the Game_Enemy objects.

Edit:
I want this to place the troop in the center of the screen. (320 - troop_width/2 maybe?)

Edit 2:
Ok, I have resolved somethine like 1/4 of the problem.
Now i have to find the smallest and the highest value in an array.
Ex: prite_x = [10,7,4,8]
The smallest value should be sprite_x[2] and the highest value should be sprite_x[0] but i think there is no methode in Array that allow this.
