Highlight of items in the Game

Hello everyone, fans of game creation, I found the time to write a short post about the highlight object shader in your projects.

If you create a game, you will need to meet the requirements of the gaming industry for your game to be accepted by players - this is the standard of success. One of the most important parts of gameplay aesthetics is its visual part. In this topic we will write a shader that highlights the player’s interactive object, this can be either an object that is located close to the player or levers on the level.

shader_type spatial;

render_mode unshaded, depth_draw_never;

uniform vec4 shine_color : source_color = vec4( 1.0, 1.0, 1.0, 1.0 );

uniform float cycle_interval : hint_range(0.5, 5.0) = 1.0;

uniform float shine_speed : hint_range(1.0, 5.0) = 3.0;

uniform float shine_width : hint_range(1.0, 100.0) = 3.0;

void fragment( )

{

vec3 vertex = ( INV_VIEW_MATRIX * vec4( VERTEX, 1.0 ) ).xyz;

float width = shine_width 0.001 cycle_interval;

float frequency = floor( sin( vertex.z cycle_interval + TIME shine_speed * cycle_interval ) + width );

ALBEDO = shine_color.rgb;

ALPHA = clamp( ( 1.0 - dot( NORMAL, VIEW ) ) frequency shine_color.a, 0.0, 1.0 );

}

That's it, in the end, you get this shader =)
