Guadiana lines

Hi,

In the attached image you can see an "error" drawing lines in navegame. I do not know if it is a problem of the code or a bug. It is trivial to replicate. Run the game and shoot at the bottom.

It also happens horizontally at certain ys, although no line is drawn at all (I guess due to the same as above).

I just had a quick look. The draw_laser() function is called all the time, even when not shooting. So it is probably drawing and clearing right away displaying only a partial line.

The correct way should be to call the function only once at the frame when the key down happens and clearing at the frame when the key up happens.
(Edit) Or at least clear line in the vertical blanking, right after v sync to avoid clearing during the display scan.

Thanks Franck,

You are right, although I am having some problems to make it work properly: it looks there is a similar issue to the others I posted when returning a custom type. I will try to get a reproducible example.

Returning a custom type is working OK for me right now. You can forget about it for the moment
