draw_roundrect

Draws a rectangle with rounded corners of a fixed radius.

语法：

draw_roundrect(x1, y1, x2, y2, outline);


参数 描述
x1 The x coordinate of the top left corner of the rounded rectangle (as if it were a normal rectangle).
y1 The y coordinate of the top left corner of the rounded rectangle (as if it were a normal rectangle).
x2 The x coordinate of the bottom right corner of the rounded rectangle (as if it were a normal rectangle).
y2 The y coordinate of the bottom right corner of the rounded rectangle (as if it were a normal rectangle).
outline Whether the rounded rectangle is drawn filled (false) or as a one pixel wide outline (true).


返回： N/A（无返回值）


描述

With this function you can draw either an outline of a rounded rectangle or a filled rounded rectangle where the (x1,y1) position is the top left corner and the (x2,y2) position is the bottom right corner. You can define how precise the drawing of the corners is with the function draw_set_circle_precision, but this function uses a fixed radius for them (should you need to change the corner radius, use the function draw_roundrect_ext()).

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_set_colour(c_lime);
draw_roundrect(50, 100, 250, 200, 0);

This will draw a filled rounded rectangle, with its theoretical (before being curved) top left corner at (50,100) and its theoretical bottom right corner at (250,200).
