Actions Documentation
AttachShader(integer programID, integer shaderID)
This action attaches a shader onto an unlinked shader program.
Parameters
BindBuffer(integer purpose, integer bufferID)
This action activates a buffer and indicates what it should be used for. The first parameter is a code, such as GL_ARRAY_BUFFER, that indicates the purpose of the buffer, and the second is an ID generated by "CreateBuffer".
Parameters
- integer purpose: A code representing what this buffer will be used for.
- integer bufferID: An ID representing the buffer that should be activated.
BindVertexArray(integer arrayID)
Parameters
ClearScreen(integer mask)
This action clears the screen with the currently stored color in OpenGL.
Parameters
ClearScreenColor(number red, number green, number blue, number alpha)
This action sets the color to clear the screen with in OpenGL.
Parameters
Compare(Libraries.Language.Object object)
This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.
Example Code
Object o
Object t
integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smaller)
Parameters
- Libraries.Language.Object: The object to compare to.
Return
integer: The Compare result, Smaller, Equal, or Larger.
CompileShader(integer shaderID)
This action compiles a shader, identified by its ID number. The shader must have already had its source code set using SetShaderCode.
Parameters
CreateBuffer()
This action returns an ID for a new buffer in the rendering system. Buffers are used to relay information from the program to the graphics card. For example, they are used by VertexBufferObjects to communicate polygons and their associated info so they can be rendered. Before a buffer created by this action can be used, it has to be activated first with BindBuffer.
Return
integer: An ID associated with a new buffer.
CreateShader(integer shaderType, text sourceCode)
This action makes a new shader of the requested type (e.g., FRAGMENT_SHADER or VERTEX_SHADER from the Shader class) using the given source code. If the shader code successfully compiles, this action will return an integer ID representing that shader. If the shader can't be created or it does not successfully compile, this will alert an error.
Parameters
Return
integer:
CreateShaderID(integer shaderType)
This action gets an ID value for a new shader of the requested type (such as FRAGMENT_SHADER from Shader).
Parameters
Return
integer:
CreateShaderProgram(Libraries.Game.Graphics.Shaders.ShaderProgram program)
Parameters

DeleteBuffer(integer bufferID)
This action deletes a buffer in the rendering system. The ID provided should be an ID that was generated using CreateBuffer.
Parameters
- integer bufferID: An ID representing the buffer to be deleted.
DeleteShader(integer shaderID)
This action instructs the rendering system to delete the native resources allocated to a shader. After deleting a shader, it can't be used by the rendering system unless it's recompiled.
Parameters
DeleteShaderProgram(integer programID)
This action instructs the rendering system to delete the native resources allocated to a shader program. After deleting a shader program, it can't be used by the rendering system unless it's reloaded. Deleting a program doesn't automatically delete the shaders attached to it -- those must also be deleted manually.
Parameters
DeleteVertexArray(integer arrayID)
This action makes a new shader of the requested type (e.g., FRAGMENT_SHADER or VERTEX_SHADER from the Shader class) using the given source code. If the shader code successfully compiles, this action will return an integer ID representing that shader. If the shader can't be created or it does not successfully compile, this will alert an error.

Parameters
- integer uniformID: An integer ID that represents a uniform in a linked shader program.
- Libraries.Containers.Number32BitArray: A typed array containing the values to copy to the uniform.
- integer startIndex: The first index of the array to begin copying.
- integer length: How many elements should be copied from the input array to the uniform array.
SetTextureParameter(integer targetTexture, integer parameterType, integer parameterValue)
Sets an option identified by the parameterType code inside the texture identified by the given targetTexture ID using the given parameterValue.
Parameters
SetVertexInputID(integer programID, integer inputID, text name)
Parameters
SetVertexInputInformation(integer inputID, integer size, integer type, boolean normalize, integer stride, integer offset)
This action informs the rendering system of how to interpret elements of vertex input data for a particular input.
Parameters
- integer inputID: An ID that describes a vertex input.
- integer size: How many bytes from the array are needed to set a single instance of the input value in the shader. Must be between 1 and 4.
- integer type: A constant value representing the type of data, such as GL_INT.
- boolean normalize: If set to true, fixed-point data values will be normalized when passed down to the system. If set to false, the values will be passed down without modification.
- integer stride: How many bytes of data separate each instance of data meant to be used for this input. If this value is 0, it's assumed that there is no additional data interleaved between data used for this input.
- integer offset: The index of the first element of this input's data in the input buffer, or in other words, how many bytes of data appear before the first instance of input data for this input.
SetViewport(integer x, integer y, integer width, integer height)
Parameters
UseDefaultVertexArray()
UseShaderProgram(integer programID)
This action tells the graphics system to render content using the shader program indicated by the provided ID.
