Ok, I posted the main loop in with this post, here are my problems, how would I go about making an object strafe (this one is probably easy to answere.)

My second problem is I have no height recognition for my terrain, how would I add it for an object.

My third problem, when jumping you can jump an unlimited ammount of time making it possible to fly, how do I limit this to a certain height.

And finally my third problem, how do I position the follow camera higher up than the box? The game im working on is a mech game so they have to stand fairly high.

Im not asking for someone to write the code for me, im asking someone to help me learn how to write codes for these subjects.

Thx much,
Zero

One effective way I get my objects, cameras to starfe is on a key press I rotate the object/camera 90 or -90 depending on which way you'd want to strafe then i'd use the Move Object command to go however far that way and then do either 90 or -90 [The opposite of the one before] to return the player to the original angle.

Ok I made something like this...



Ive also tried it with all directions x y and z, and I still dont get good results. It either moves me forward, up, or makes me do a 180. Any idea to why its not working?

Thanks,
Zero

Oh sorry I probably should of mentioned a few points.

The object should be rotated on the Y axis.
Well heres some source code I've taken out of my current project as an example.



The code moves a camera instead of an object but the basic idea is the same.

Hmmm, I tried it with just a camera, and the code made a 90 degree turn and faced me in that direction, any clue why this is going on?

Ill post my new code in the source again...

Thanks,
Zero

YRotate Camera() does rotate the camera by that amount it rotates it to that ammount so, Your code should be....

ok, there's a little bit involved with your questions, so forgive me if i don't remember all the code exactly. firstly, most of your questions can be answered in the monster hunt tutorials, look there for things like strafing. here's my exact code for strafing from one of my fps.
IF KEYSTATE(30)=1
x#=newxvalue(x#,wrapvalue(angy#-90.0),2.0)
z#=newzvalue(z#,wrapvalue(angy#-90.0),2.0)
ENDIF
keystate(30) is the "a" key. the x# is the player coordinate. newxvalue generates a new x-coordinate value for a position from a given point and angle. basically, you enter the current position, enter the angle to move (which in this case is angy# - 90 degrees, or directly to the left of the camera angle), and the final parameter is the distance to move. see if that works out for you.

for your second question:
if by height recognition you mean that your mech walks through the matrix instead of over the top of it, you need to use the "get ground height command". syntactically, it goes as follows:

y# = get ground height(matrix number, x position, y position)

then reposition your character at its given x,y,z coordinates

i'll get to jumping in a minute. as for your camera problem, don't use the default follow camera command. instead, position the camera at a point behind the player and adjust it to whatever height you want, then tell the camera to always point at the player. (you'll need to use newxvalue and newzvalue commands)
for example
camy#=y#+50 (or however high you want your camera to be above your mech)
camz# = Newzvalue(z#,angy#-180,camdist#)
camx# = Newxvalue(x#,angy#-180,camdist#)
position camera camx#,camy#,camz#
point camera (x#,y#,z#)

as for jumping, i assume that you already have gravity in effect. all you need is a simple control variable, set to 0 or 1. if they hit the jump key, set the control to 1 and put an if statement restricting further jumping until the variable equals 0. when they return to the ground, set the variable equal to 0

Ok, so how about camera jumping, how is that done? Is it done with camera position y or something?

I decided to go with the good old fassioned camera movement for a start, and I have no clue how to bring about jumping.

Thanks,
Zero

P.S. Before I was using the code that yellow sent me a link to.
