I have this code to get my character to move around the map. But I am missing one thing, jumping. Can someone help me in coding a jump function?

+ Code Snippet

   If UpKey()=1 or k$="W"
      XRotate Object ColliderObjNum,0
      Move Object ColliderObjNum,Delta#
      XRotate Object ColliderObjNum,cx#
   EndIf

   If DownKey()=1 or k$="S"
      XRotate Object ColliderObjNum,0
      Move Object ColliderObjNum,0-Delta#
      XRotate Object ColliderObjNum,cx#
   EndIf

   If LeftKey()=1 or k$="A"
      XRotate Object ColliderObjNum,0
      YRotate Object ColliderObjNum,cy#-90
      Move Object ColliderObjNum,Delta#
      YRotate Object ColliderObjNum,cy#
      XRotate Object ColliderObjNum,cx#
   EndIf

   If RightKey()=1 or k$="D"
      XRotate Object ColliderObjNum,0
      YRotate Object ColliderObjNum,cy#-90
      Move Object ColliderObjNum,0-Delta#
      YRotate Object ColliderObjNum,cy#
      XRotate Object ColliderObjNum,cx#
   EndIf

Do something like this (pseudo code):

+ Code Snippet

rem before your main loop -------------------

rem values...
jumpforce#=2.0
gravforce#=0.1

rem in your main loop --------------------

rem jump with space
if spacekey()=1 and grav#=0 then grav#=jumpforce#

rem control gravity
dec grav#,gravforce#
inc PlayerPosY#,grav#

rem collision detection
if <player collides with ground>
   <reposition>
   grav#=0
endif
