Force field with glowing contact lines
In your harnessGodot shaderMIT
Additive energy shield that brightens at its silhouette, carries moving bands, and glows where it cuts through other geometry, found by comparing its depth with the scene depth buffer.
What it takes and gives
- Shader type
- spatial
- Render modes
- unshaded, blend_add, cull_disabled, depth_draw_never, shadows_disabled
- Parameters
- depth_texture (sampler2D), field_color (vec4 = 0.3, 0.7, 1, 1), base_strength (float = 0.06), rim_power (float = 3), rim_strength (float = 1.1), contact_width (float = 0.18), contact_strength (float = 2.5), band_frequency (float = 14) and 2 more
- Use it on
- Opaque geometry intersecting the shield; transparent objects are not in the depth buffer.
- Result
- A faint blue bubble with a bright outline, moving bands and bright lines where it cuts the floor and objects.
- Renderers
- compatibility: compiled and rendered, forward plus: not verified, mobile: not verified
- Placement
- res://baltor/godot_shaders/force_field_intersection/
Limits. The contact test compares depths along the view ray, so the glow band widens where the shield meets a surface at a shallow angle. Additive blending cannot darken. Depth reconstruction uses the CURRENT_RENDERER define to pick the depth range convention; only the Compatibility path ran.
