A constructor defined in BBMOD_TerrainMaterial.gml
Extends BBMOD_BaseMaterial
new BBMOD_TerrainMaterial([_shader])A material that can be used when rendering terrain.
| Name | Type | Description |
|---|---|---|
| _shader | Struct.BBMOD_Shader |
A shader that the material uses in the BBMOD_ERenderPass.Forward pass. Leave undefined if you would like to use BBMOD_Material.set_shader to specify shaders used in specific render passes. |
| Name | Description |
|---|---|
| AlphaBlend | Use true to enable alpha blending. This can have negative effect on performance, therefore it should be used only when necessary. Default value is false. |
| AlphaTest | Discard pixels with alpha less than this value. Use values in range 0..1. Default value is 0.9. |
| Anisotropy | The maximum level of anisotropy when BBMOD_Material.MipFilter is set to tf_anisotropic. Must be in range 1..16. Default value is 16. |
| BaseOpacity | A texture with a base color in the RGB channels and opacity in the alpha channel. |
| BaseOpacityMultiplier | Multiplier for BBMOD_Material.BaseOpacity. Default value is BBMOD_C_WHITE. |
| BlendMode | A blend mode. Default value is bm_normal. |
| Culling | A culling mode. Default value is cull_counterclockwise. |
| Filtering | Use false to disable linear texture filtering for this material. Default value is true. |
| IsLoaded | If false then the resource has not been loaded yet. |
| MipBias | Defines a bias for which mip level is used. Can be also negative values to select lower mip levels. E.g. if mip level 2 would be normally selected and bias was -1, then level 1 would be selected instead and if it was 1, then level 3 would be selected instead. Default value is 0. |
| MipFilter | The mip filter mode used for the material. Use one of the tf_ constants. Default value is tf_anisotropic. |
| MipMax | The maximum mip level used, where 0 is the highest resolution, 1 is the first mipmap, 2 is the second etc. Default value is 16. |
| MipMin | The minimum mip level used, where 0 is the highest resolution, 1 is the first mipmap, 2 is the second etc. Default value is 0. |
| Mipmapping | Use one of the mip_ constants. Default value is mip_markedonly. |
| OnApply | A function that is executed when the shader is applied. Must take the material as the first argument. Use undefined if you do not want to execute any function. Defaults to undefined. |
| Path | The path to the file from which was the resource loaded, or undefined if the resource does not come from a file. |
| Persistent | If true then the resource is persistent and it is not destroyed when method free is used. Default value is false. |
| RenderPass | Render passes in which is the material rendered. Defaults to 0 (no passes). |
| RenderQueue | The render queue used by this material. Defaults to the default BBMOD render queue. |
| Repeat | Use true to enable texture repeat for this material. Default value is false. |
| ShadowmapBias | Controls range over which the mesh smoothly transitions into shadow. This can be useful for example for billboarded particles, where harsh transition does not look good. Default value is 0, which means no smooth transition. |
| TextureOffset | An offset of texture UV coordinates. Defaults to (0, 0). Using this you can control texture's position within texture page. |
| TextureScale | A scale of texture UV coordinates. Defaults to (1, 1). Using this you can control texture's size within texture page. |
| TwoSided | Whether the material is two-sided. If the material is two-sided, normal vectors of backfaces are flipped before shading. Default value is true. |
| ZFunc | The function used for depth testing when BBMOD_Material.ZTest is enabled. Default value is cmpfunc_lessequal. |
| ZTest | If true then models using this material should be tested against the depth buffer. Defaults value is true. |
| ZWrite | If true then models using this material should write to the depth buffer. Default value is true. |
| Name | Description |
|---|---|
| apply | Makes this material the current one. |
| clone | Creates a clone of the material. |
| copy | Copies properties of this material into another material. |
| destroy | Frees memory used by the struct. |
| free | Releases a reference to the resource. |
| from_buffer | Loads the resource from a buffer. |
| from_file | Loads the resource from a file. |
| from_file_async | Asynchronnously loads the resource from a file. |
| from_json | Loads material properties from a JSON object. |
| get_shader | Retrieves a shader used in a specific render pass. |
| has_shader | Checks whether the material has a shader for the render pass. |
| ref | Retrieves a reference to the resource. |
| remove_shader | Removes a shader used in a specific render pass. |
| reset | Resets the current material to undefined. |
| set_base_opacity | Changes the base color and opacity to a uniform value for the entire material. |
| set_shader | Defines a shader used in a specific render pass. |
| to_buffer | Writes the resource to a buffer. |
| to_file | Writes a resource to a file. |
| to_json | Saves material properties to a JSON object. |
