Shield impact ripple from a hit point
In your harnessGodot shaderMIT
Show an impact on a spherical shield: a flash at the hit direction and a ring that travels over the sphere along great circles and fades, looping on a timer or driven by a script.
What it takes and gives
- Shader type
- spatial
- Render modes
- unshaded, blend_add, cull_disabled, depth_draw_never, shadows_disabled
- Parameters
- shield_color (vec4 = 0.25, 0.6, 1, 1), impact_color (vec4 = 1, 0.85, 0.5, 1), hit_azimuth_degrees (float = 25), hit_elevation_degrees (float = 15), impact_progress (float = 0.35), loop_impacts (bool = yes), loop_period (float = 1.5), ring_width (float = 0.12) and 3 more
- Use it on
- A sphere centred on its origin. To aim at a world hit point, convert it to the object's local direction in a script and set the two angles.
- Result
- A faint blue bubble with a bright ring spreading out from the impact point.
- Renderers
- compatibility: compiled and rendered, forward plus: not verified, mobile: not verified
- Placement
- res://baltor/godot_shaders/shield_hit_ripple/
Limits. One impact at a time; several simultaneous hits need several materials or an array uniform. Directions are taken from vertex positions, so the mesh must be roughly spherical around its origin. Additive, so it cannot darken.
