![]() How much brighter to make a medium brightness pixel. How much brighter to make a low brightness pixel. What brightness (between 0 - 1.0) to consider a pixel as medium brightness. What brightness (between 0 - 1.0) to consider a pixel as low brightness. How many pixels up/down to sample next to the sample pixel. How many pixels left/right to sample next to the sample pixel. How much you consider neighboring pixels when sampling. How much you consider the current pixel when sampling. 0.5 means half.ġ.0 means regular contrast. 0.5 means half.ġ.0 means regular brightness. Hue / Saturation / Brightness / Contrast Property Nameġ.0 means regular saturation. Use the following properties to adjust a shader's behavior after creation by either setting the values directly or tweening them, as specified right above. Specifying a Shader Inline (inside a Design Mode block)Īlternatively, for convenience, you can specify a shader's source directly within Design Mode using the shader from text block. The engine automatically assumes that the shaders are under the extras folder, so need to mention that. For example, if your shader is called bloom.glsl, then you type bloom.glsl into the block. Refer to your shaders using the shader from file block.glsl in this example) under that extras folder. Stick the shaders (file extension doesn't matter - we use. (Debug > View > View Folder for this Game) Importing a Shader from a FileĬreate an extras folder inside your game's main folder. As mentioned earlier, shaders are written in GLSL and must comply with the OpenFL ES 2.0 standard. Stencyl comes with a sizable variety of shaders, but for the adventurous, we allow you to apply your own custom shaders. Note: All property names are case sensitive. How do you figure out the property names? Refer to the Property Reference section later in this article. Using our built-in blocks, you can instantly set properties and tween them (change them over time). For example, if you're using a Contrast shader, you'll want to change the contrast amount. Sometimes, you want to modify a shader's properties in real-time (or before application). To turn off shaders, use the clear shaders from game block. Use the shader + shader block to accomplish this. Multiple Shadersīy combining multiple shaders into a single, composite shader, you can apply all of these shaders at once. This block lets you opt the HUD layer out of shaders. To apply a shader, use the following block and insert any shader into the lone field, like this:Īll shader blocks can be found under Scene > Shaders.Īside: What does the toggle shaders for HUD layer block do? Since shaders apply to the entire screen, this can sometimes be undesirable if those effects are also applied to a game's HUD (such as the health/score display). Since our engine is based on OpenGL ES 2.0 (in order to support mobile targets), the syntax is more restricted than normal GLSL. Shaders are written in GLSL, a programming language that your graphics card understands. They work to a limited extent on Android. Shaders are not supported on Flash or iOS. All of this is hardware accelerated, so within reason, you can accomplish a lot.Combine as many shaders together as you want, within reason.Alter a shader's properties at runtime.They aren't all that different from the filters you apply to an photo in Instagram or Photoshop. Shaders are filters that apply visual effects to the entire screen. ![]()
