character made of large sprites won't talk

[tweety]

Hi there, work with "Keepers of Knowledge" is going on well, but there is one thing:
I have a pretty large character (actually it's a normal-sized character sitting in a train) who has to talk (that's why I made it a character, not an object). after the dialog, the train departs.

but now the character moves his lips only sometimes, not during the whole sentence - although I set him up just like all the others. the lip movements are different every time I test the game... sometimes he doesn't move his lips at all, sometimes twice or even more times.

Is it possible that the sprites are too large, so that the engine can't show them in time? Or what could be the reason?

you may have accidently set the time which a certain frame is displayed longer than the other frames...

I thought of that already, but that isn't the reason...
some more ideas?

Hmmm this is rare, but may still be possible, try enabling FPS display and see if your game is running at full speed, add the following line to game_start() of your game:

Debug(4,1);

What's the res and colour depth of your game?

Alternately, you don't need to draw the who character as sprite if you don't need movements in other part of the body, just draw him on the background and make the face a character.
