You need sliding collision to stop it from gettin stuck on objects... It's DBC's inbuilt collision that stuff's up... it isnt designed to cater for sliding collision so you have to make collision boxes or something like that
Here is a good example (You'll notice its actually a DB help file, hehe):

rem DARK BASIC EXAMPLE PROGRAM 25
rem ==========================================
rem This program shows use of object sliding
rem collision and simple gravity influences
rem ------------------------------------------
autocam off : sync rate 60
hide mouse : sync on
rem Make four walls
make object box 1,10,200,1000 : position object 1,-500,100,0 : color object 1,rgb(155,40,20)
make object box 2,10,200,1000 : position object 2, 500,100,0 : color object 2,rgb(155,40,20)
make object box 3,1000,200,10 : position object 3, 0,100,-500 : color object 3,rgb(155,40,20)
make object box 4,1000,200,10 : position object 4, 0,100, 500 : color object 4,rgb(155,40,20)
rem Make a floor and create texture for it
make object box 5,1000,10,1000 : position object 5,0,-5,0 : color object 5,rgb(0,255,0)
create bitmap 1,32,32 : cls rgb(0,155,0) : ink rgb(0,145,0),0 : box 4,4,12,12
get image 1,0,0,32,32 : delete bitmap 1 : texture object 5,1
scale object texture 5,200,200
rem Make a pedestal steps

rem Make a player object (and a non-rotated collision box for it)

make object collision box 11,-5,-5,-5,5,5,5,0
disable object zdepth 11
rem Make the pedastal use non-rotated box collision
for t=0 to 4
make object collision box 6+t,-25,-4,-25,25,4,25,0

rem For fun, slightly move pedastal step
