yet again i need some help

I am yet again having some problems with my game. i wanted to add a projectile for my character to throw so i did this.
SET WINDOW 0,543,327,0
PLOT 144,141;235,141
PLOT 174,141;168,133
PLOT 174,141;168,149
PLOT 168,133;217,133
PLOT 217,133;235,141
PLOT 168,149;217,149
PLOT 217,149;235,141
PLOT 187,141;183,133
PLOT 187,141;183,149
PLOT 200,141;194,133
PLOT 200,141;194,149
PLOT 213,141;207,133
PLOT 213,141;207,149
PLOT 226,141;217,149
PLOT 226,141;217,133
BOX KEEP 144, 168, 174, 235 in feather$
LET x = 144

FOR move = 1 to 50
BOX CLEAR x, x+1, 174, 235
LET x = x + 2
BOX SHOW feather$ at x,174
NEXT move

I want it to shoot across the screen but it keeps just dissapearing. also how would i make it where when it hits an enemy it stops and sticks in them? any help would be greatly appreciated.



Ok Thanks for the help

The last part of your program should be as follows:

BOX KEEP 144, 235, 149,133 in feather$
LET x = 144
FOR move = 1 to 50
BOX CLEAR x, x+2, 149, 133
LET x = x + 2
BOX SHOW feather$ at x,149
NEXT move

You need to understand that BOX KEEP requires the co-ordinates left,right,bottom,top, whereas in your original code you were using the PLOT statement co-ordinates which are left,bottom,right,top. As a result you were BOX KEEPing a blank area of the screen - this is why your image kept disappearing.
