8/5/2023 0 Comments Gamemaker docs2 get hue![]() ![]() I will update this shader to a partial hue shift when I feel like it. This value should be a value between 0 and 255. This could be set in create event or step event or whatever you desire. ![]() Shader_set_uniform_f(u_hue, (-hue/255)*(pi*2)) Īll that's left is setting the "hue" variable. If you don't wanna shift, but just set the hue, remove the float originalHue = atan(圜olor.b, 圜olor.g) line and then remove originalHue + in the next line.Ĭreate event: u_hue = shader_get_uniform(shHueShift, "hue") //Change this to whatever name you gave your shader.ĭraw event: shader_set(shHueShift) //Change this to whatever name you gave your shader. This also allows for coloring a black and white sprite. Create event: uhue shadergetuniform (shHueShift, 'hue') //Change this to whatever name you gave your shader. This uses YIQ to shift hue, as HSV might give some problems. if you dont wanna shift, but just set the hue, remove the float originalHue atan (圜olor.b, 圜olor.g) line and then remove originalHue + in the next line. They are also among the most advanced features offered by GameMaker Studio 2, but I will try to explain everything as simply as possible in this post. Shaders are often used to create beautiful graphical effects in games. Gl_FragColor = vec4(yiq2rgb*yFinalColor, 1.0) Written in November 2017 by Alejandro Hitti, a video game programmer and designer from Venezuela. Vec3 yFinalColor = vec3(圜olor.r, chroma * cos(finalHue), chroma * sin(finalHue)) Vec3 圜olor = rgb2yiq * texture2D(gm_BaseTexture, v_vTexcoord).rgb įloat originalHue = atan(圜olor.b, 圜olor.g) įloat chroma = sqrt(圜olor.b*圜olor.b+圜olor.g*圜olor.g)
