Breaks, speeding into the up direction.

[PutPixel255]

Hi I'm just wondering why the code breaks when I push the space button while traveling in the up direction. Only happens when space is pushed.

this seems to be key ghosting issue? (tho i find it weird that it would happen on 2 keys when it normally happens with 3 or more)

I guess I'll rewrite the clamping code or use the up dated framework anyway moving on. If its not a problem with the logic.

I ran this on my machine and all was well except for the same issue i had, was when i press left - up - space, the space key gets nulled and doesn't respond but only with that 3 key combo. I since used the "S" key to replace the space in my code and all 3 key combos work now. I did a little digging and it seems to be the keyboard mappings on the keyboard its self.

I wonder if that test app could be embedded on the FAQ page or something.

Yes that's a good page actually. I'mma gonna bookmark that one ..

((D3DCOLOR*)rect.pBits)[ x + (rect.Pitch >> 2) * y ] = D3DCOLOR_XRGB( r,g,b );

Not sure why this is pushing the reticle north of the border into the forbidden zone.


is this >> dividing by 4. i'm just guessing.

well this seems to wrap upwards correctly when I stuck a 12 in there.
The debugger showed a neg 2 for y so perhaps that explains 12 working, but what about the other 5 positions plus the height of the reticle.



// 12 is the magic number
if(y<12)
{
y=594;
}
if(x>794)
{
x=5;
}
if(y>594)
{
y=12;
}

I checked your code. It's all about logical ordering: You want to first move, then clamp, and not the other way round. Plus it's not really "clamping" if you teleport to the other side. The original code should work perfect if you'd just switch to move first, then clamp.

Thanks Lux your the man. And now I am free to teleport across the cosmos which is 800x600. Yea, I wrote that from memory so I got it backwards and thought about why it didn't and did work. and now I am tired cause thinking is hard. Winky face.
