In your harnessGodot shaderMIT

Run a bright diagonal shine band across a sprite at intervals, masked by the sprite's alpha, with control of angle, width, softness, speed and the pause between sweeps.

The render its check recorded in Godot 4.7.2, 256 by 256 pixels.

What it takes and gives

Shader type: canvas_item
Parameters: shine_color (vec4 = 1, 1, 0.95, 1), angle_degrees (float = 30), band_width (float = 0.14), softness (float = 0.5), intensity (float = 0.9), sweep_time (float = 0.8), pause_time (float = 1.4), progress_override (float = -1)
Use it on: A Sprite2D (or other textured CanvasItem) with transparent space around its shape, assigned to the node as usual.
Result: The sprite with a bright diagonal band of light across its middle.
Renderers: compatibility: compiled and rendered, forward plus: not verified, mobile: not verified
Placement: res://baltor/godot_shaders/sprite_shine_sweep/

Limits. The band moves in UV space, so in an atlas it sweeps across the whole atlas region. It brightens additively and can clip on light sprites.
