3.1.3
11e14e5

This release mainly adds per-vertex ambient (split into upper and lower hemisphere), directional and point lights and per-pixel fog into the default shaders, imitating the classic GameMaker 3D look.

Changelog:

GML API:

Core module:

  • Added new functions bbmod_light_ambient_set, bbmod_light_ambient_get_up, bbmod_light_ambient_set_up, bbmod_light_ambient_get_down and bbmod_light_ambient_set_down using which you can configure color of the ambient light sent to shaders.
  • Added new struct BBMOD_Light, which is a base class for dynamic.
  • Added new struct BBMOD_PointLight, which is a dynamic point light.
  • Added new functions bbmod_light_point_add, bbmod_light_point_count, bbmod_light_point_get, bbmod_light_point_remove, bbmod_light_point_remove_index and bbmod_light_point_clear using which you can configure point lights sent to shaders.
  • Added new struct BBMOD_DirectionalLight, which is a dynamic directional light.
  • Added new functions bbmod_light_directional_get and bbmod_light_directional_set using which you can configure directional light sent to shaders.
  • Added new struct BBMOD_ImageBasedLight, which casts light from RGBM-encoded prefiltered octahedrons onto the scene.
  • Added new functions bbmod_fog_set, bbmod_fog_set_color, bbmod_fog_get_intensity, bbmod_fog_set_intensity, bbmod_fog_get_start, bbmod_fog_set_start, bbmod_fog_get_end and bbmod_fog_set_end using which you can configure fog properties passed to shaders.
  • Added a new functions bbmod_ibl_get and bbmod_ibl_set using which you can configure image based light sent to shaders.
  • Added new methods on_set and on_reset to BBMOD_BaseShader, which are executed when the shader is set/reset. These are now used in derived shaders to set global shader uniforms instead of misusing method set_material.
  • Added new methods set_ambient_light, set_directional_light, set_point_lights and set_fog to BBMOD_Shader, which are called automatically in on_set to pass defined lights and fog to the shader.
  • Added new functions bbmod_camera_get_position and bbmod_camera_set_position using which you can configure the camera position sent to shaders.
  • Deprecated variable global.bbmod_camera_position, please use the new functions instead.
  • Added new functions bbmod_camera_get_exposure and bbmod_camera_set_exposure using which you can configure the camera exposure value sent to shaders.
  • Deprecated variable global.bbmod_camera_exposure, please use the new functions instead.
  • Added new functions bbmod_render_pass_get and bbmod_render_pass_set using which you can configure the current render pass.
  • Deprecated variable global.bbmod_render_pass, please use the new functions instead.
  • Added new macros BBMOD_C_AQUA, BBMOD_C_BLACK, BBMOD_C_BLUE, BBMOD_C_DKGRAY, BBMOD_C_FUCHSIA, BBMOD_C_GRAY, BBMOD_C_GREEN, BBMOD_C_LIME, BBMOD_C_LTGRAY, BBMOD_C_MAROON, BBMOD_C_NAVY, BBMOD_C_OLIVE, BBMOD_C_ORANGE, BBMOD_C_PURPLE, BBMOD_C_RED, BBMOD_C_SILVER, BBMOD_C_TEAL, BBMOD_C_WHITE and BBMOD_C_YELLOW, which are shorthands for new BBMOD_Color().FromConstant(c_aqua) etc.
  • Added new method BBMOD_Color.FromHex using which you can initialize a color using RRGGBB hexadecimal format.

Rendering module:

PBR submodule:

  • Using material BBMOD_MATERIAL_SKY does no longer implicitly load sky and IBL sprites from the included files! You will need to do that yourself if you want to use the PBR shaders!
  • Moved methods set_cam_pos and set_exposure from BBMOD_PBRShader to BBMOD_Shader. These are also called in the on_set method.
  • Method BBMOD_PBRShader.set_ibl now optionally takes a BBMOD_ImageBasedLight to pass to the shader. When not specified, it defaults to the one defined using bbmod_ibl_set. Call of this method was also moved to on_set.
  • Deprecated functions bbmod_set_ibl_sprite and bbmod_set_ibl_texture. Please use the new struct BBMOD_ImageBasedLight and function bbmod_ibl_set instead.
