I need help with bullet types in 2d to create a bullet

if you need the tiles mail me.

OK, your problem is that you need to treat the bullet Type like a place-holder description. Then for each bullet you want you must create an instance of the bullet Type to use.

i.e. when they press space the following needs to be done:

;create an instance of bullet type
b.bullet=New bullet

This assigns the variable 'b' as a bullet type and assigns a new bullet place-holder to it. Then to access each of the fields within b (as it is now a bullet Type) you do the following:

;set x to 0
b\bullet_x=0 

;set y to 0
b\bullet_y=0 

;set left to false
b\bullet_left=False 

Now the other 2 important things to know about types is how to go through all the different instances you have created and manipulate them and also how to delete them.

To go through each bullet instance you've created you would do the following:

;go through all the bullets created
For b.bullet=Each bullet
    If b\bullet_left 
        b\bullet_x=b\bullet_x-le 
        b\bullet_x=b\bullet_x+ri 
        b\bullet_y=b\bullet_y-do 
        b\bullet_y=b\bullet_y+u2 
    EndIf 
Next

To delete a bullet you simply use Delete var.bullet where var is the variable currently assigned with the bullet you want to delete.

;delete all bullets
For b.bullet=Each bullet
    Delete b
Next

It's not a full explanation but should help. There's some more text in your help files under Tutorials I think.
