Method: MiniGL::Res.imgs

Defined in:
lib/minigl/global.rb

.imgs(id, sprite_cols, sprite_rows, global = false, ext = '.png', retro = nil, tileable = false) ⇒ Object

Returns an array of Gosu::Image objects, using the image as a spritesheet. The image with index 0 will be the top left sprite, and the following indices raise first from left to right and then from top to bottom.

Parameters:

id

A string or symbol representing the path to the image. See img for details.

sprite_cols

Number of columns in the spritesheet.

sprite_rows

Number of rows in the spritesheet.

global

Set to true if you want to keep the image in memory until the game execution is finished. If false, the image will be released when you call clear.

ext

The extension of the file being loaded. Specify only if it is other than “.png”.

retro

Whether the image should be loaded with the ‘retro’ option set (see Gosu::Image for details). If the value is omitted, the Res.retro_images value will be used.
