Trying to make a new boss, but I don't know if this method is viable. It's an alien centipede type thing.
I spawn the head and the head spawns the next segment and so on. Each segment to follow to previous... but it runs SLOW.
Is this method even workable? All together it is composed of 6 sprites.
The self.direction are to do with images when they are all set up, and not the movement. The monster just moves in a square, but ultimately I just want to command the head and the rest should/does follow, just the slowdown is unplayable. Is it better to just have a bunch of separate segments with the same movement logic so they only appear to be connected? I'd like to maybe make this creature playable at some point, that's why I picked this method.
Ideas? Thanks.

Do you have a full runnable example of the game?

Sort of. I'll add a help panel and a boss test mode. Then it can be played through with the working boss or test the second. I'll link it here in a few hours.

How do you know this is the slow part ? Did you profile code ?

Here is what I have. It's a big game, and primitive, but pretty fun. It still uses my old tile map any has plenty bugs, but most features are there.
It will hopefully run as is. You start at top and blast away blocks looking for money to get upgrades and the R, G, and B keys. Then fight a boss. Did lots of the art myself.
Run as is and play it through to kill the working boss.
Change line 114 in main.py to "boss_room2" and the end boss will be the one I posted.
Pressing "p" will give you all upgrades and warp you to boss chamber.
press "h" for controls.

I'll look at what you posted here, Winspar.
Let me know if this doesn't run so I can fix it and re-upload.

I will have to disable your sound. My computer doesn't like your wav sound files.

linux is case sensitive. Im not changing every single image/sound filename to the correct loaded string name associated with it. For example:
metulburr@ubuntu:~/Downloads/Block_Miner_original$ python3 main.py
pygame 1.9.6

oh.. I thought I got all those, just for that reason. I fix it right now. Sorry.

I used Bfxr for most the sounds. Does it make strange files maybe? I don't reall know how I fix that problem.

There. Pretty I got them all this time.

I create a bfxr wav file. Download it. It works fine.
I try your wav file. There just error.
Your ogg files work fine.

I was using the standalone version. I make the sounds locally and export it to my snd folder. They all work for me. I'm going to stop that. Is it python that gives you an error or did you try them with your media player too? The ogg files were all downloads.
