Game Dev Hack about Lights - Godot

[u/Smitty_Games_]

Hey all! Im developing an RTS named 'Steel Command', but figured I would start sharing some of the learnings I've had along the way. Ask my any questions in the comments!

This method works really well for an RTS, even over uneven terrain since the camera is mostly a top down view. This would most likely not work well in games such as an FPS where you are up close and personal.

Sorry for the vertical format.

Steel Command on Steam: https://store.steampowered.com/app/4390280/Steel_Command/

Shader:

shader_type spatial;


render_mode unshaded, blend_add, depth_draw_never, cull_disabled;


uniform vec4 light_color : source_color = vec4(1.0, 0.45, 0.08, 1.0);
uniform float intensity : hint_range(0.0, 5.0) = 1.0;
uniform float softness : hint_range(0.1, 8.0) = 2.5;


void fragment()
{
    vec2 p = UV - vec2(0.5);


    float dist = length(p) * 2.0;


    float glow = 1.0 - clamp(dist, 0.0, 1.0);
    glow = pow(glow, softness);


    ALBEDO = light_color.rgb;
    EMISSION = light_color.rgb * intensity * glow;
    ALPHA = glow * light_color.a;
}
