### Re: 2D shadows

Big big big thankyou! You're welcome sero! :-) I'll see if I can dig out some more stuff. Now I just need to crack the 2d shadow problem, or I won't be able to sleee again... Edit: I noticed that you initially revived this thread in search of line to circle tangent intersection. This type of proble...

### Re: 2D shadows

That's a great example, sero :-) In retrospect I am sorry for having not written a more elaborate reply regarding the SAT algorithm. My main point here is: the idea of SAT is casting the shadow of a pair of objects on a flat surface for every vertex, and if there is a ray of light between any of tho...

### Re: 2D shadows

Looks great! I am completely certain that you can do this with pure vector math (no cos / sin / sqr / atan2) by modifying the Separating Axis Theorem (SAT), which is used for very fast geometrical object collision detection. Google is your friend.

### Re: fbgfx versus opengl graphics

With lang fb it's in namespace FB fb.GET_WINDOW_TITLE works. That's it! Forgot the namespace. Should have learned by now not to code when tired. So, to turn on open gl back end rendering, you simply calll: ScreenConrtol fb.SET_GL_2D_MODE Without parameters? I tried the following before secreenres, ...

My Mistake: Here in the Screen Control: https://www.freebasic.net/wiki/wikka.php?wakka=KeyPgScreencontrol You can set OpenGL as the backend driver for FBGFX. I'm having a little trouble deciphering the info from the link and getting this to work. I keep getting the following error. "error 42: ...

No, they aren't using FB in-house. But, I'll be pestering my colleagues about how awesome it is, and maybe some day they'll give in :-)

Hello folks, This was a great read, thanks for a super tutorial on just exactly the topic I was searching for! Can you tell me what the best strategy is for sending large amounts of data between a running FB application and an Arduino? Basically I want to update a group of member vars in a type inst...

It's at a small company that develops sensor hardware and writes all software from low-level controller code to customer user interfaces in the house. So, it's a mixed bag, but to begin with I think it will be mostly high-level stuff.

Hello folks,

I just wanted to tell you this. Yesterday I was at a programming job interview, and I only used FreeBASIC code examples to show my skills. And I got the job! :-)

Cheers, Mike

### Re: Function parameter call by reference?

Thanks. This confirms what I thought, that it should simply be @w, @h, but this returns a suspicious pointer warning and doesn't work. So, I'm guessing there may be a small error either in the original code or in the FB SDL header.
