SetLayerMask
From Spheriki
Sets a tint color for a map layer.
Contents |
Usage
- layer Number, non-negative. The map layer index of the layer to tint.
- mask Sphere Color object. The colour to tint to.
Examples
Let's create a map of a high-altitude mountain pass. We want the base layer, on which the player can walk, and a lower layer, containing the parallax scrolling of a dark forest, shrouded by mist. We will only concentrate on the mist part for simplicity's sake, and assume the tiles, obstructions and parallax settings have already been handled.
Let layer 0 be the parallax 'mist' layer, and layer 1 be the base layer upon which the player can walk. We place this inside the map's SCRIPT_ON_ENTER_MAP event, using the editor:
var mist_color = CreateColor(192, 192, 255, 128); SetLayerMask(0, mist_color);
This will create a very flat, simple mist that only tints the lower level, while leaving the upper level clear.
Notes
- When setting a tint color, be sure that the color has an alpha value less than 255, otherwise the layer will appear completely opaque.
- In terms of color masking, this uses the color averaging scheme, so a black pixel on a layer with this effect applied may not appear as black after tinting.
- If tinting is desired for the whole map, considering using the ApplyColorMask() function.
