moving a boulder

[dxfan101010]

Ok so iam making a game with maps using matrices for all of the hit detection. I have both money and movement working but i want to add a boulder that you can move around by pushing around from all four sides. I have tried several times but my code seemes large and bulky i was wondering if anyone would be willing to help me. i am using matrix A for anyone who cares A=1 for a wall A=3 for money

and im asuming ur using Xlib's/Celtic+Xlib's Matrix tile mapper right? Well in this case, when the boulder detects it has been hit, record the last movement you had, so.. idk how ur doing ur movement.. but try to add a variable for the X Coordinate (and i dont mean the one ur using for coordinates.. i mean like.. say... Speed.. is S, is X going to go +1 or -1 (Right, or Left)? so like say S was ur movement variable.. and X is what u actually use for the Xcoordinate.. S+X->X.. So if u were moving Right>> S=1, if u moved left, S=-1, and then same goes with Y..) Im not really quite sure where im going with this, cause u wouldnt be able to tell which movement happened.. X_X nvm.. idk.

EDIT: Now that i look at this, its really confusing, i was thinking of like 5 ways to do this at the same time =D..
For example.. for my Bouncing ball Game, i have Speed = S, and my Y coordinate = Y

Everytime i had a loop, S would decrease by .01 or something, and if i pressed up, S would increase by .1, So what i would do is.. S+Y->Y (say its going down.. -3+50->Y..Y would become 47..) so with the 'S' you would know which direction the Y coordinate just traveled (Of course ur 'S' isnt gonna be any higher then 1, or lower then -1)

No i dont have a lib on my caculator its in pure basic i am doing an 8*16 map
xxxxxxxxxxxxxxxx
x & x
x x
x x
x x
x x
x x x * x
xxxxxxxxxxxxxxxx
&=guy
x=wall
*=exit
i want to add a o as a bolder

sorta like this
sorry for being unclear

Edit : well sorta like that map but with spaces

First of all, what method do you use for collision detection? (With the walls, of course)

[dxfan101010]

I use the getkey codes and then test


if [A](X,Y)=1


1 is a wall x,y is player
if it does than i restore the old x and y if it doesn't i move the character

X → S
Y → Q
X+(k=34 And X<-(k=25and X>0 )→ X
Y+(K=26 and Y ≤ 16)-(K=24 ≥1)→ YIF [A](X,Y)=1: Then
S → X
Q → Y
End
Outout(x,y,"m

Store a variable in the matrix for a boulder. When you update the coordinate of your player, don't change the actual coordinate, but use 'surrogate coordinates'. Check if there's a boulder on that location, next, check if the coordinate at your current coordinate + twice the 'movement function' is free. If so, update your player's coordinate with the movement function, and the boulder coordinate with the same movement function.
I tried working it out but I'm to tired right now. I'll try again tommorow.
I once made a game with movable boulders, but I used pxl-test instead of matrices witch works quite good, using a matrix is a little more complicated but I guess it's doable.

Ok its not that big a deal it was a challenge from a friend that i thought id give a try

[GloryMXE7]

heres an easy way to determine if a Location is in bounds using only one if statement

if (16-X)*(X-1)≥0 And (8-Y)*(Y-8)≥0
then (X,Y) is in bounds
for the graph screen you just change 16 to 94,8 to 62,and the ones to zeros.
