Node that casts light in a 2D environment. Node that casts light in a 2D environment. Light is defined by a (usually grayscale) texture, a color, an energy value, a mode (see constants), and various other parameters (range and shadows-related). Note that Light2D can be used as a mask. Return the color of the Light2D. Return the energy value of the Light2D. Return the height of the Light2D. Used with 2D normalmapping. Set the maximum layer value of objects of the scene that are affected by the Light2D. Get the minimum layer value of objects of the scene that are affected by the Light2D. Return the current mode set to the Light2D. Return the shadow buffer size. Return the color of casted shadows for this Light2D. Return the texture of the Light2D. Return the offset of the light texture. Return the scale value of the light texture. Get the maximum Z value that objects of the scene can be in order to be affected by the Light2D. Get the minimum Z value that objects of the scene have to be in order to be affected by the Light2D. Return true if the Light2D is enabled, false if it is not. Return true if shadow casting is enabled for this Light2D, else return false. Set the color of the Light2D. Switches the Light2D on or off, depending on the 'enabled' parameter. Set the energy value of the Light2D. The bigger the value, the stronger the light. Set the height of the Light2D. Used with 2D normalmapping. Set the item mask of the Light2D to 'item_mask' value. Set the item shadow mask to 'item_shadow_mask' value. Set the maximum layer value of objects of the scene that are affected by the Light2D. Set the minimum layer value of objects of the scene that are affected by the Light2D. Set the behaviour mode of the Light2D. Use constants defined in the constants section. Set the shadow buffer size. Set the color of casted shadows for this Light2D. Enable or disable shadows casting from this Light2D according to the 'enabled' parameter. Set the texture of the Light2D. Set the offset of the light texture. Set the scale value of the light texture. Set the maximum Z value that objects of the scene can be in order to be affected by the Light2D. Set the minimum Z value that objects of the scene have to be in order to be affected by the Light2D. Adds the value of pixels corresponding to the Light2D to the values of pixels under it. This is the common behaviour of a light. Subtract the value of pixels corresponding to the Light2D to the values of pixels under it, resulting in inversed light effect. Mix the value of pixels corresponding to the Light2D to the values of pixels under it by linear interpolation. The light texture of the Light2D is used as a mask, hiding or revealing parts of the screen underneath depending on the value of each pixel of the light (mask) texture.
