draw_line

Draws a line one pixel wide.

语法：

draw_line(x1, y1, x2, y2);


参数 描述
x1 The x coordinate of the start of the line.
y1 The y coordinate of the start of the line.
x2 The x coordinate of the end of the line.
y2 The y coordinate of the end of the line.


返回： N/A（无返回值）


描述

With this function you can draw a 1 pixel wide line between any two points in the game room.

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_line(50,50,150,50);

This will draw a light green horizontal line from point (50,50) to point (150,50).
