I'm just getting started but would really appreciate some help with a problem i have. I have animated a figure moving right left and jumping (though these are not the final animations, just to test the code). But when the character changes direction the animation dosen't change straight away.

I havent got much code yet so ive posted it all.

Thanks.

instead of using "gosub" for every action the little dude does. Do the action within the "if upkey()=1" and "endif" commands. You can also use functions, functions are probably faster in large numbers than gosubs, well gosubs win, in a sub-routine, which jumping, sorta is'nt. But if you really dont care that much about speed, which this is obviously about, slap a goto instead of a gosub, but if its in a loop (it has to be) make sure you make a function or something that continues the loop.

i think you're right the if/endif commands are better for these actions and i have changed the code.

I dont think i explained the problem very well though. When I press the right key, the sprite moves right and has the correct animation. But if i then press left the remaining frames from the right animation play before it changes to the left animation. It changes straight away when i press right from going left though.

Hey hey hey,

I still could do with a hand if anyone's interested, and here's a revised version of the animation code...



This is within a do/loop. Please please please, somebody help me.

Uh... I may be barking at the moon here but your if statements for the image selection are not correct. Unless I'm very much mistaken, you can't do a if 2<x<10 statement and get it to work correctly in the manner you want it to. The proper format is if 2<x and x<10, because the term of 2<x returns either a zero or one, which will then be tested against the <10 value. Both in moving left and moving right, you have this mixed comparison, which could explain your failing animation.

Any truly great code should be indisguishable from magic.

Yep, SandraD is right.

and if you want to stop the animation NOW, then do it like this:
