Don't forget that all GDI calls use PIXELS so convert your coordinates if necessary.

Fantastic!! Exactly what I was looking for.<br />
Not tested in the game yet, but seems perfect, I hope it's fast enough not to slow down the game! I let you know.<br />
<br />
I thank you so much!

Hi guys,<br />
<br />
I'm writing a small 2D car game in VB. I have problems finding out a good (and FAST) code to determine if the car (x,y) is on or out of the road.<br />
What I've done is divide the road in many regions composed by a number of lines (usually 4 lines), and I set the lines as invisible.<br />
Now I need the code to determine if the car is inside one of the polygons or out of them.<br />
<br />
Data:<br />
Region1(line1(x1,x2,y1,y2)<wbr />, line2(x1,x2,y1,y2), &nbsp;line3(x1,x2,y1,y2), ...)<br />
Region2(line1(x1,x2,y1,y2)<wbr />, line2(x1,x2,y1,y2), &nbsp;line3(x1,x2,y1,y2), ...)<br />
....<br />
Car(x,y)<br />
<br />
<br />
If you suggest any faster way to do what I'm looking for feel free, it will be very appreciated. Please if possible post the code.<br />
Thanks

Determine if a point (x,y) is internal or external a region composed by n(3,4,5...) lines.

Visual Basic is Microsoft’s event-driven programming language and integrated development environment (IDE) for its Component Object Model (COM) programming model. It is relatively easy to learn and use because of its graphical development features and BASIC heritage. It has been replaced with VB.NET, and is very similar to VBA (Visual Basic for Applications), the programming language for the Microsoft Office product line.
