How is one supposed to animate sprites? I.E. make a sprite alternate between two sprites each 0.5 secs.I'm having a lot of trouble for something that was so simple in ptc. Any help?

I just finished teaching someone else, so head there for details. https://miiverse.nintendo.net/posts/AYMHAAACAAADVHkkBvGXZg The short answer is to use the SPANIM function. For example put this in line 3: SPANIM, 0, "I", 30, 3108, 30, 3109, 30, 3112, 0 (I put three sprites to show you it can alternate between more than two)
