![]() You have to add a section in the XML file for each variable you need to retrieve/change from the Clickteam Fusion 2.5 events and properties. ![]() Optional, defines global variables that you can use in your shader function. And you will need to add these images as parameters in your XML file. Start from register(s2) if you also use a background image sampler. If your shader accesses other images, add one sampler2D per image : You will need to specify 1 in your XML file, see below. If your shader needs to access the background, add the following sampler2D for the background texture : This is the minimum global variable to define in a shader, it contains a 2D sampler associated with the texture passed to the shader (the object's image).Note: if you prefer, you can also just use a float4 value instead of defining a PS_OUTPUT structure with a single float4 member inside. This structure defines the output value of the pixel shader function. Those coordinates are UV coordinates, between 0 (left/top) and 1 (right/bottom). ![]() The Texture variable contains the X and Y coordinates of the pixel in the texture being processed. This structure defines the input parameters passed to the pixel shader function. Note: Clickteam Fusion 2.5 only supports pixel shaders, it doesn't support vertex shaders. It's a VERY simple shader that you should easily understand. If you have never made a pixel shader, we suggest that you look at the source code of the Horizontal Flip effect of Clickteam Fusion 2.5 (FlipX.fx/xml files in the Clickteam Fusion 2.5 Effects directory) while you are reading this documentation. the global variables used by the shader.the definition of input / output data structures.fx file is a source code file that usually contains :
