Why would it need to by Dynamic?

(to metalgearhunter) No no, see... Dynamic sprites are the ones that rotate 360 degrees or have smooth growing/shrinking animations, for example. For example, YI Chomp Rocks are Dynamic. So are the SMW normal boss enemies when you defeat them (how they spin around and shrink). Baseball Boys wouldn't need to be dynamic to work.

(to Knight of Time) That doesn't sound too hard to make, but I have a lot of sprite requests on my shoulders right now... How badly do you need it?

Ok, I'll try making the tick, since I don't really feel like making any of those custom (not in any real game) requests right now, or whatever was in my custom title for a short period of time. I might make one that isn't dynamic, and I also might make a dynamic version

You're better off making a brand new sprite for that instead of basing it off the SMB3 Nipper. They're set up entirely different-- they just happen to use the same graphics.

The concept for that would be to, every x frames, check to see if Mario is within a certain range, and set the Y Register to 00 if he is. Otherwise, check for a wider range, and if he's in that range set Y to 01. Otherwise check for an even WIDER range, set Y to 02 if positive, otherwise set Y to 03.

Then, check to see if Mario is to the left of the sprite, and if he is, add 4 to the Y register.

Set up an 8-value Table that has the possible X speeds of the fireball. The first 4 should be going to the right, starting with the lowest value and going to the highest. The next 4 values should be for the leftward movement (which means from FF to 80), again, slowest to fastest.

Then, in the fireball-shooting routine, when you're setting the fireball's X speed, have it select the X speed from the Table as an index of Y.

This should produce the exact same effect as in SMB3, as long as you set the Table values correctly. It would take some experimentation, plus you actually have to write the code too, so...

Oh, by the way, you can copy the code from my Shower Panser's fireball routine for a quick way to get it to shoot a fireball. Just change the RNG speed chooser with your Distance-Table speed chooser.

The rest is the easy part.

Hope that helps.
