Alright, I'm starting off to right my new game in xLib, but I'm having a problem when I move the character. When he moves left, his right arm makes a continuous line, and it won't move up or down. (Note: I'm new to xLib).
Included here is a .rar with the program, the 2 pic files needed, and a screenshot. (The PTI .gif file).

Thanks.

hmm lemme take a look at it.

EDIT: I like the .zip name

EDIT 2: Well, I got the dude to move up and down, but he still leaves lines

I tried redrawing the sprite, moving every pixel 1 pixel to the left. Now his left arm leaves a line. It seems which pixel is the one the very edge, it leaves a line. :

could you post the source over here? so it should be easier for the non ti graph link user to help with code

Here's the source:

c1-->

CODE

ec1real(0
35->X:35->Y
[[0,0,0,0,0,0,0,0,0,0,0,0][0,0,0,0,0,0,0,0,0,0,0,0] [0,0,0,0,0,0,0,0,0,0,0,0][0,0,0,0,0,0,0,0,0,0,0,0] [0,0,0,0,0,0,0,0,0,0,0,0][0,0,0,0,0,0,0,0,0,0,0,0] [1,1,1,1,1,1,1,1,1,1,1,1][1,1,1,1,1,1,1,1,1,1,1,1->[A]
real(2,0,0,0,12,8,0,12,7,8,2,0,8,1
Repeat 0
real(8
real(1,X,Y,1,8,1,0,0,0,0,1
If Ans:Then
X+(Ans=3)-(Ans=2)->X
Y+(Ans=1)-(Ans=4)->Y
End
Endc2

are you sure xLIB getkey 1 = Basic getkey 34 and xLIB getkey 4 = Basic getkey 25?

EDIT:Haha man i just thought of the reason. You need to have the real(2,0,0,0,12,8,0,12,7,8,2,0,8,1
In the loop. I'm pretty sure that'll fix it.

DJ Omnimaga · « **Reply #6 on:** January 21, 2007, 06:35:00 am »

yeah now you are erasing the display with the map only before the loop start, you need to run it every time it loops

Cure, You could save some bytes w/ this:

c1-->

CODE

ec1
:{8,12} -> dim([A]
:Fill(0,[A]
:For(A,1,12
:1 -> [A](7,A)
:1 -> [A](8,A)
:End
c2

ec2

Jon: Thanks for the optimization.

I changed the code to this:
c1-->

CODE

ec1real(0
35->X:35->Y
[[0,0,0,0,0,0,0,0,0,0,0,0][0,0,0,0,0,0,0,0,0,0,0,0] [0,0,0,0,0,0,0,0,0,0,0,0][0,0,0,0,0,0,0,0,0,0,0,0] [0,0,0,0,0,0,0,0,0,0,0,0][0,0,0,0,0,0,0,0,0,0,0,0] [1,1,1,1,1,1,1,1,1,1,1,1][1,1,1,1,1,1,1,1,1,1,1,1->[A]
real(2,0,0,0,12,8,0,12,7,8,2,0,8,1
Repeat 0
real(2,0,0,0,12,8,0,12,7,8,2,0,8,1
real(1,X,Y,1,8,1,0,0,0,0,1
real(8
If Ans:Then
X+(Ans=3)-(Ans=2)->X
Y+(Ans=1)-(Ans=4)->Y
End
Endc2

But, it still makes that line, and I can't move up and down. :

I've had some of these funny problems, too. Try to store the Ans variable into another variable right after the loop (like Z) and replace all the (Ans=...) with (Z=...). It might work, but I'm not sure, for I, too, am a beginner at xLib

CureDesu · « **Reply #10 on:** January 21, 2007, 12:34:00 pm »

Delnar, I tried your suggestion. It worked, in that I can now move in all directions, but my guy is still dragging a lot of lines. Could it be because of the drawing logic?

Delnar_Ersike · « **Reply #11 on:** January 21, 2007, 12:42:00 pm »

I think the problem there is that you are not erasing all of the sprite. I don't know how to fix that: I've never encountered that problem before.

The problem that was just fixed had to do with the:
X+(Ans=3)-(Ans=2)->X
Y+(Ans=1)-(Ans=4)->Y

The first (Ans=...) parts overrided the previous number in Ans, so the second part couldn't function correctly.

Alright, thanks to xlibman's help, I got it working. For those who want to know, here's what I do: I set it so if a key is pressed, the it displays the same sprite in the same spot with XOR logic, (without updating the LCD (same with the map)), then I update the coordinates and display the sprite in the new position. Thanks for everyone's help.

no problem

glad i could help

Hope your game can be something we can enjoy!
