This is probem:

I made project with camera movement on matrix and strafing, but when I press "W" for move camera forward, camera is going forward, but falling down...simillar problem when I want back "S"...but in this case...camera is going back and gaoing more and more in air.. xD

And just one more problem...when I Hold "W+A" "W+D" "S+A" and "S+D" camera has normal movement, but unnormal speed...

This is Code:

+ Code Snippet


Sync On : Sync Rate 60 : Hide Mouse 

Make Matrix 1,100,100,100,100

Position Camera 50,2,0

z#=camera position z (0)
    
Rem : Little strange strafing xD I found it on forum :)
do
    
If Keystate (17) then Move Camera z#+0.05

If Keystate (31) Then Move Camera z#-0.05

if keystate(30)
turn camera left 90
move camera 0.05
turn camera right 90

endif
If Keystate(32)
turn camera right 90
move camera 0.05
turn camera left 90
Endif

sync
loop

You need to point the camera straight ahead after you position it. Regarding the movement, typically moving on the diagonal is faster, but here is a way you could do it so the amount moved is the same.

Sync On : Sync Rate 60 : Hide Mouse

Make Matrix 1,100,100,100,100

Position Camera 50,2,0
point camera 50,2,200
z#=camera position z (0)
    
Rem : Little strange strafing xD I found it on forum :)
do
    k17 = keystate(17) : k31 = keystate(31)
    k30 = keystate(30) : k32 = keystate(32)
    if k17 = 1 : // moving forward
        if k30 = 1
            turn camera left 90
            move camera 0.025
            turn camera right 90
            Move Camera z# + 0.025
        endif
        if k32 = 1
            turn camera right 90
            move camera 0.025
            turn camera left 90
            Move Camera z# + 0.025
        endif
    endif
    if k31 = 1 : // moving backward
        if k30 = 1
            turn camera left 90
            move camera 0.025
            turn camera right 90
            Move Camera z# - 0.025
        endif
        if k32 = 1
            turn camera right 90
            move camera 0.025
            turn camera left 90
            Move Camera z# - 0.025
        endif
    endif
    If k17 = 1 and k30 = 0 and k32 = 0 then Move Camera z# + 0.05

If k31 = 1 and k30 = 0 and k32 = 0 Then Move Camera z# - 0.05
    if k30 = 1 and k17 = 0 and k31 = 0
            turn camera left 90
            move camera 0.05
            turn camera right 90
    endif
    if k32 = 1 and k17 = 0 and k31 = 0
            turn camera right 90
            move camera 0.05
            turn camera left 90

EDIT: Code was edited. Fixed it so you can move left / right if either one of them is the only key being pressed.

So many games to code.......so little time.
