This line is not necessary, `yet it helps us to tweak the speeds of our character to get it just right easily. Object_Speed#=1 do `Initialize our loop ` "X" is the x position "1" is the object number ` and "#" tells the comiler we're working with numbers. ` These variables can be whatever you like, yet I like having a standard method that ` you can easily identify what each variable is for, and what object it applies to. x1#=object position x(1) y1#=object position y(1) z1#=object position z(1) ` Same principles as above, yet the "a" stands for angle, "y" for the type of angle ` and the "#" tells the comiler we're working with numbers. ay1#=object angle y(1) `The reason we initialized the variables above, was so we could use the `set camera to follow command. This lets the camera follow the object `located at the x position(x1#), y position(y1#) and z position (z1#) `We've also added the object angle y(ay#), so that when the object turns, the camera `will re-adjust to the proper angle. set camera to follow x1#,y1#,z1#,ay1#,5,5,1,1 `These two commands tell the object to move forward with the up and down keys. `Again, you'll see the Object_Speed# variable, that determines how fast they go. if upkey()=1 then move object 1,Object_Speed# if downkey()=1 then move object 1,-Object_Speed# `We use our object angle y(ay#) variable here to determine whether the object `turns left or right. if leftkey()=1 then rotate object 1,0,(ay1#)-1,0 if rightkey()=1 then rotate object 1,0,(ay1#)+1,0 sync `Refresh the screen loop ` Loop the program `You now have the basis of a follow cam tutorial. `Hope this helped -Mike- `Copyright(c) 2004 Curved Basic |
