Syntax Breakdown
| Name | Type | Description |
|---|---|---|
| index | integer (number) | The index number to assign to the light source. Index starts at 0. |
| type | integer (number) | The type of light you want to create. 0 = spotlight. 1 = point light. |
| pos | point (x, y, z) | The position of the light source. Z controls how close the light source is to the screen. Lower value = closer. |
| targ | point (x, y, z) | The target position of the light source. The light travels from pos to targ. Only for point lighting; set {0,0,0} for spotlight. |
| falloff | point (cnst, lnr, quad) | The falloff controls the amount of light decay over distance. Please see here for more details on light attenuation. |
| ac | point (r,g,b) or function (h,s,v) | This allows you to apply an ambient color to the light source. It uses RGB by default but you can use HSV instead if you prefer by using the hsv() function. |
| dc | point (r,g,b) or function (h,s,v) | Diffuse color is similar to ambient color, but it is used to tint the screen itself, as opposed to just the light source. |
| df | float (decimal) | The diffuse factor controls the strength of the diffuse color. 1 = default. Higher than 1 = brighter. Lower than 1 = darker. |
| exp | integer (number) | The exponent controls the spread of light from the source. 0 = 180º whereas an higher value will have a smaller spread. This parameter is only required for spotlights. |
| cutoff | float (decimal) | The cutoff is used to define how soft or sharp the edges of the light will be. The value should be between 0 & 1. This parameter is only required for spotlights. |
