If I have an object (2d) at coords OBJECTX,OBJECTY moving at any angle (0 - 360) at velocity `VEL`.
How do I calculate the DELTAX,DELTAY value to add to OBJECTX,OBJECTY coords to allow me to move the object?

cheers!

 COS() and SIN()

PlayBASIC Code: [Select]

 setfps 60
 Angle#=rnd(360)

 Speed#=2 
 
 x#=400
 y#=300
 
 do
   cls 0

; option 1    
;   x#=x#+cos(angle#)*Speed#   
;   y#=y#+sin(angle#)*Speed#   
;   circle x#,y#,10,true 


; option 2
;   x#=x#+cosRadius(angle#,Speed#)   
;   y#=y#+sinRadius(angle#,Speed#)   
;   circle x#,y#,10,true 

; option 2
   x#=cosNewValue(x#,angle#,Speed#)   
   y#=sinNewValue(y#,angle#,Speed#)   
   circle x#,y#,10,true 


   if spacekey() then angle#=rnd(360)
 
    Sync
 loop
