Delta timing and tile scrolling

BlitzMax Forums/BlitzMax Programming/Delta timing and tile scrolling

Hi !

To Games coders gurus...

I use delta timing into my code. This works fine but, i've a pb with my smooth vertical 32x32px tiles scrolling.

Display tiles at _floating positions_ (scrollY# = ScrollY# + Delta# * ScrollingSpeed#) produce some tiles overlay or an 1 px blank line between two tiles rows (see picture). Do you think that i must choose another timing algorithm (avoid delta timing) to scroll the tiles at integers positions ?

This Screenshoot illustrate my problem (image heavy, so follow the link) :
