POPython Roguelike: Inventory Disappears
text
Body
copied!<p>Today I progressed further into <a href="http://roguebasin.roguelikedevelopment.org/index.php?title=Complete_Roguelike_Tutorial,_using_python%2Blibtcod" rel="nofollow">this Python roguelike tutorial</a>, and got to the inventory. As of now, I can pick up items and use them. The only problem is, when accessing the inventory, it's only visible for a split second, even though I used the <code>console_wait_for_keypress(True)</code> function. I'm not sure as to why it disappears. Here's the code that displays a menu(in this case, the inventory):</p> <pre><code>def menu(header,options,width): if len(options)>26: raise ValueError('Cannot have a menu with more than 26 options.') header_height=libtcod.console_get_height_rect(con,0,0,width,SCREEN_HEIGHT,header) height=len(options)+header_height window=libtcod.console_new(width,height) libtcod.console_set_default_foreground(window,libtcod.white) libtcod.console_print_rect_ex(window,0,0,width,height,libtcod.BKGND_NONE,libtcod.LEFT,header) y=header_height letter_index=ord('a') for option_text in options: text='('+chr(letter_index)+')'+option_text libtcod.console_print_ex(window,0,y,libtcod.BKGND_NONE,libtcod.LEFT,text) y+=1 letter_index+=1 x=SCREEN_WIDTH/2-width/2 y=SCREEN_HEIGHT/2-height/2 libtcod.console_blit(window,0,0,width,height,0,x,y,1.0,0.7) libtcod.console_flush() key=libtcod.console_wait_for_keypress(True) index=key.c-ord('a') if index>=0 and index<len(options): return index return None </code></pre> <p>I'd appreciate anyone's help or input to this problem.</p>
