Earthbound Backgrounds

Description

This is a free asset to create backgrounds similar to those seen in earthbound.

There's a short manual and every script is documented. And three included demos should help you get started.

HOW TO USE:

• Create a background sprite. It has to be square, on a seperate texture page and its origin should usually be centered.
• If you want to use colour ramps to colourize, then also create a colour-ramp sprite. It has to be square and on a separate texture page, but can be rather small. Usually 8x8 pixels is great already. Draw a gradient on at least one row of pixels. Each row can be a separate colour-ramp.
• Create a controller object.
• In its create event, call scr_earthbound_create(). This will create an instance of obj_earthbound_backgrounds and return its ID. Store this ID in a variable so you can destroy the background objects later.
• Also in create event you can set, what sprite to use and how to draw it by calling these scripts:
  • scr_earthbound_bg_set_position()
  • scr_earthbound_bg_set_image()
  • scr_earthbound_bg_set_gpu()
  • scr_earthbound_bg_set_scale()
  • scr_earthbound_bg_set_movement()
  • scr_earthbound_bg_set_col_ramp() Check each script for more details.
• Still in create event you ccan also set the destortion effects by calling these scripts:
  • scr_earthbound_bg_set_wave_x()
  • scr_earthbound_bg_set_wave_y()
  • scr_earthbound_bg_set_stretch_x()
  • scr_earthbound_bg_set_stretch_y() Check each script for more details.
• Also call scr_earthbound_bg_set_view_size() whenever the size of the target you're drawing upon changes. i.e. when the application surface changes.
• If you want more layers on your background, you can do that from the same controller object. Just call scr_earthbound_create() and all the other scripts you need to change the background for each layer.
• Whenever you don't need the backgrounds anymore, destroy all background instances created with scr_earthbound_create() and then destroy the controller instance.
