Render Ground

Render Ground (23 June, 2026)

This object is responsible for drawing the perspective horizon to create a three-dimensional effect relative to the plane on which the camera is located; entire effect is achieved using a shader applied to the object.

Render Ground object(s) are created by via Tails7 Info Object -> Startup Set Render; number of them may depend on the screen resolution.
For example, for a resolution of 640x480 or other resolutions with a 4:3 aspect ratio, 3 objects will fit:

It is not possible for copies of objects to be distributed along two axes at the same time; there are only three cases in which objects will be created:

When the width is greater than the height; the object is scaled to the height and fills the width
When the height is greater than the width; the object is scaled to the width and fills the height
When the height and width are the same, only a single copy is created (1:1 aspect ratio)

Using this technique, you can easily add support for resolution changes by adjusting the Frame Width, Frame Height, and window size.

You can also add support for 4K (But in Mode 7, why? But it’s possible! Unless the GPU can’t handle it)

Note

If the game uses a renderer that does not support advanced effects, the object will not be invisible sprites.
