A TextureMatrix, or texmat, when applied to a material object, allows you to define how a texture will appear in a material. It can be used to manipulate still (fixed) textures as well as animated ones.
textureMatrix name example_texmat scale 0.0 0.0 1.0 1.0 # u/v freqs, u/v scales spin 0.0 # rotation freq shift 0.0 0.0 # u/v freqs center 0.5 0.5 # dynamic u/v center (for spin and scale) fixedscale 0.0 0.0 # time invariant u/v scale fixedspin 0.0 # time invariant rotation fixedshift 0.0 0.0 # time invariant u/v shift end
The valid parameters for textureMatrix are:
- Name of the texmat, for reference
- Causes texture to dynamically change it's size, parameters are u/v frequencies, then u/v scales.
- Cause a texture to spin around a center point, parameter is rotational frequency.
- Causes texture to move linearly, parameters are u/v frequencies.
- Central point for spin and scale
- Fixed scale, texture doesn't move with time.
- Fixed spin, texture doesn't move with time.
- Fixed shift, texture doesn't move with time.
A textureMatrix can be called by adding 'texmat <name>' to a material containing a texture, like so:
material name example_material diffuse 1 1 1 1 texture caution texmat example_texmat end
The Texture Matrix can only be added to a map by hand, or by pyBzEdit.
The TextureMatrix object was added with the v2.0.0 release of BZFlag.
