| I know this topic is over discussed, but I have tried several methods and none have worked. Again to late to post code, but is there any common tricks that work? |

I don't know what graphics are flickering.
It is Plot command, Text(, Ouput(, gray with xlib?
I need to know to give more specific tips. |

Flickering is caused by an excessive time delay between the erasing of old pixels and the drawing of new ones.
Ideally, a sprite shouldn't update if nothing about it has changed.  |

Hmm I see. And it tends to be when using Output and Pxl. I tend to not use point because the differences bewtween it and pxl-test.
And I usually have the code something like:
:4->A
:8->B
:Lbl1
:Output( A,B,"X"
:0->K
:While K=0
:getkey->K
:End
:Output(A,B," "// One space and a,b are my coordinates for character.
: A+(K=34)-(K=25)->A
:B+(K=26)-(K=24)->B
:Goto 1 |

The solution is to only erase your graphic (by Outputting a blank space) when that graphic moves around, like Weregoose said.
Anyway, here is an unrelated point, but regarding the use of Pt- and Pxl- commands: http://tibasicdev.wikidot.com/friendly-window
Specifically, try running
:ZStandard
:84→Xmin
:-72→Ymin
:ZInteger
and compare the Pt- and Pxl- commands.

No, you are checking everything. Since K<24 or K>26 is always true, it will check everything.
Try this: K=/34 and 1<abs(K-25 |

Hmmm. Thanks. I almost made a stupid post though. I was gonna say if k=24 then that wont work, before remembering the right key is 24. |

Just pointing something I noticed earlier out
Code:
0->K
while K=0
getkey->K
End
is really slow compared to
Code:
repeat Ans
getkey
End
Ans->K
and to save a few bytes (although it's a wee bit slower)
Code:
repeat K
getkey->K
End
