거의 내 부스 상품을 만들기 위해서 만든 코드들이다
https://ahzkwid.booth.pm/
몇개는 개인작 하다가 만든정도
자주 쓰는 간단한 코드들만 적어놨다
두 값이 다른지 검사
if(!all(vec1 - vec2))
//위아래동일(all은 -1도 true로 반환하기 때문)
//(vec1 != vec2)
if(length(vec1 - vec2)<0.01) //가끔씩 미세한 변화로 인해 인식 안될때 사용
if(!((vec1.x==vec2.x)&&(vec1.y==vec2.y)&&(vec1.z==vec2.z)))
에미션
color.rgb = lerp(color.rgb,1 , _EmitionColor.rgb);
uv가 0~1을 벗어났는지 검사
