画多边形命令
pygame.draw.polygon |
polygon(Surface, color, pointlist, width=0) -> Rect
Surface:图形,color:颜色,pointlist:坐标点列表,width:线宽。返回矩形对象。 |
画圆形命令
pygame.draw.circle |
circle(Surface, color, pos, radius, width=0) -> Rect
pos:圆形中心坐标点,radius:半径 |
画直线命令
pygame.draw.line |
line(Surface,color,start_pos,end_pos,width=1) -> Rect
start_pos:起始坐标点,end_pos:结束坐标点 |
画折线命令
pygame.draw.lines |
lines(Surface, color, closed, pointlist, width=1) -> Rect
closed:是否封闭,如果为True,那么起点和终点将会连接。 |
画反锯齿直线命令
pygame.draw.aaline |
aaline(Surface, color, startpos, endpos, blend=1) -> Rect
最后一个blend是混合参数,它会把Surface和线条指定的颜色进行像素运算。并且这个命令无法指定线宽。 |
画反锯齿折线命令
pygame.draw.aalines |
aalines(Surface, color, closed, pointlist, blend=1) -> Rect
closed:是否闭合,pointlist:坐标点列表。 |
