draw_rectangle_colour

Draws a rectangle, either as a one pixel outline or filled-in, with each of the four corners a separate colour (creating a gradient across the shape).

语法：

draw_rectangle_colour(x1, y1, x2, y2, col1, col2, col3, col4, outline);


参数 描述
x1 The x coordinate of the left of the rectangle.
y1 The y coordinate of the top of the rectangle.
x2 The x coordinate of the right of the rectangle.
y2 The y coordinate of the bottom of the rectangle.
col1 The colour of the top left corner.
col2 The colour of the top right corner.
col3 The colour of the bottom right corner.
col4 The colour of the bottom left corner.
outline Whether the rectangle is an outline (true) or filled in (false).

描述

With this function you can draw either an outline of a rectangle or a filled rectangle by defining an area where the (x1,y1) position is the top left corner and the (x2,y2) position is the bottom right corner. If it is filled you can define the individual colours for each corner point and if these colours are not the same, you will get a gradient effect from one to the other (the colour settings will over-ride the base colour set with the function draw_set_colour).

NOTE: If you are wanting to draw a shape using a shader, you should be aware that most shaders expect the following inputs: vertex, texture, Colour. However, when using this function, only vertex and colour data are being passed in, and so the shader may not draw anything (or draw something but not correctly). If you need to draw shapes in this way then the shader should be customised with this in mind.



例如：

draw_rectangle_colour(50, 50, 200, 200, c_black, c_white, c_black, c_white, false);

This would draw a filled-in square with a smooth black/white gradient between the corners.
