So I've always used the standard battle system but my current project would'nt really work with that I want my character to be able to fight using dual pistols in the map against other shooters like in doom just in rpgmaker 2003 how is that possible to do what would l need?

In RM2k3 that is a little difficult. I seen a few games where people made a system where you "shoot" in the direction of your enemy, however it was merely a roll to see if you hit or not. It will require a lot of eventing, you cannot have many enemies per room since you may have to monitor each enemy's X,Y coordinate. In all Honesty, it's easier to do on RMXP because of scripting.
However I did do some experimenting on this, as far as I got you need to make an event that monitors the direction you face, that will tell which way the projectile needs to go. You also need to monitor the X,Y coordinates of the projectile and also the enemy events. The same must be done for the enemy projectiles.

sorry for the late reply I lost my link to this site

so its alot easier with xp ok if I upgrade to xp can I still use my same title sets and sprites from 2003?

You would have to convert them to work within XP's resource specifications. But once you do that, you should be able to use them.

Pretty much a conversion.. then you want to search the scripts section for some scripts on doing projectiles I know there are a few there.

how do I convert them cause this is hampering my progress

converting is as simple as making sure your charset is properly sized and has 4 steps instead of 3. you need to read the help files for size requirements

watch the video and download the demo... it is a shooting system that involves event and map id and even uses the terrain...

I tried to download the link in the description but mediafire wouldn't let me download it said I didn't have permission even tried making an account still wouldn't let me
