Help with drawing water across...

[Zonar Games]

I'm using Game Maker 6.1, and in my beach level I'm trying to figure out an easier way to draw water across a certain y axis across the whole level. So can anyone help me draw a rectangle with the image blend of 0.5 and draw it across a certain y axis in the level? I can't figure out how to do it.

draw_set_alpha(0.5);
draw_set_color(c_blue);

if( view_yview+view_hview >= global.water_level)
    draw_rectangle(view_xview , max( view_yview,global.water_level ) ,
                   view_xview + view_wview , view_yview + view_hview , 0 );

You could probably do it without the max (just substiture global.water_level) and you could use a min with the view_yview+view_hview, but this way makes the most sense to me.

Edit: come to think, you might see a small streak at the bottom if the water's bellow the screen and probably wastes a tiny bit of time (though I doubt much), so I added an if statement.

Thanks Kain, I'm going to test it out.

Here's an alternative to what Kain mentioned:

EDIT:

x = view_xview;
y = max( floor(objPlayer.y) - view_hview, global.water_height, view_yview );

draw_set_alpha( 0.5 );
draw_set_color(c_blue);
draw_rectangle( floor(x), floor(y), 
view_xview + view_wview, view_yview + view_hview, false );
draw_set_color(c_white);
