Hi all this is my mod and its a repulsor gun and you kill stuff whit it(Obvious...). note that this is my second mod dont expect that i am an expert i am very nooby in my mods.

The sprite problem is because it is out of palette.

and what is that supposed to mean? can u fix this for me? i would be very happy if u could!

Check the stickied topics in mod-making. It is incredibly important that you learn these skills.

i changed every single pixel using thi palette and it did still not work... why is that so?

Read the stickies again. The file has to be indexed.
Specifically, this one.

thanks all for helping me out i just dont understand that it will work if u paste ur picture over it... well anyway thanks

Another couple of suggestions: Make sure your posts are grammatically correct and clear, so that we know how exactly to respond. You're more likely to get help or whatever else you want if we know what it is that you want.
Also, if you could change the title of the thread itself to be a little more descriptive, I know I'd appreciate it. Chances are that you'd get more attention for your mod that way, too.

EDIT: Oh! And you'll want to post an image of your mod. It's in the rules, which are generally good to follow.

Mod releases require pictures in most cases, please use the minor mod dump for single item mods unless they are really good.

He might want feedback on his mod to improve...

He could also merge his various minor mods into one thread. It seems to be a popular sort of thing to do, which simultaneously allows him critique, keeps the subforum uncluttered, and makes him seem even more proliferous.

I agree with that. kind of like thesoupiest!
