I have read darkdreads RPG-tutorial on how to make an map and a character who the player can move with the arrow keys.... now i want to change the charakter and i dont just want to use circles( i want lines also) but when i try the game get screwed so can someone explain to me how to change it and NOT screw the game

this is the code for the charakter:

Code:

    X% = PlayerX% * 20                  ' This little routine draws our
    Y% = PlayerY% * 20                  ' character in the right position
    CIRCLE (X% + 9, Y% + 9), 9, 40      ' on the screen.
    PAINT (X% + 9, Y% + 9), 40, 40
    CIRCLE (X% + 5, Y% + 6), 3, 31
    PAINT (X% + 5, Y% + 6), 31, 31
    CIRCLE (X% + 13, Y% + 6), 3, 31
    PAINT (X% + 13, Y% + 6), 31, 31
    CIRCLE (X% + 5, Y% + 6), 0, 16
    CIRCLE (X% + 13, Y% + 6), 0, 16
    CIRCLE (X% + 4, Y% + 17), 2, 4
    PAINT (X% + 4, Y% + 17), 4, 4
    CIRCLE (X% + 14, Y% + 17), 2, 4
    PAINT (X% + 14, Y% + 17), 4, 4
    CIRCLE (X% + 9, Y% + 9), 2, 16
    PAINT (X% + 9, Y% + 9), 16, 16

Without fully understanding how your game is getting screwed I'll have to guess, so try reading this and copying the code etc: http://faq.qbasicnews.com/?blast=DoubleBufferingConcepts

well this is the prolem...

if i change the first circle(CIRCLE (X% + 9, Y% + 9), 9, 40 )
to: LINE (X% + 9, Y% + 9)-(X% + 9, Y% + 9), 9, BF
then you only can see the charakters eyes and everything is red
and when i move u can see the part of the map where the charakter is but if you move 2 or 3 steps more everything gets
red again... that is the prolem

Check paint's last parameter. It specifies which colour will be the limit. It will surpass any other colour. That's your problem.

Because the border colour for the body (I presume you are painting the body red, not the windshield) is not one colour. There will be a hole and so paint keeps filling past it. That's why I don't like and hardly ever use PAINT. It's better to make the actual image and PUT it to the screen (with the lovely WAIT &H3DA command to eliminate flicker).

In the tutorial that barok's has provided, as well as mine, it explains why you do want a double buffer.

The explanation is simple: using double buffering, you draw to a piece of memory instead to screen. Then, you draw the whole buffer (that piece of memory) to screen, so graphics aren't seen until they are fully drawn. When you do animations, you constatly erase stuff and draw it somewhere else. If you don't double buffer your animation, it will flicker, as the player will see how stuff is deleted and then repainted. If you do this outside the screen, the erasing/repainting process is kept hiden and the user just sees the finished image just after the next, thus obtaining an illusion of movement.
