okay, how do I walk on a randomized matrix? I need to be on top of it, not flying right trough it, your character in the game can't just fly through ground.... I tried to use the get ground height command and it gave some pretty unexpected results, so now I'm willing to use get matrix height command, but then it wants to know which tile, well the tiles were I'm walking on stupid PC

If anyone else knows of a way to simply code a way of walking on TOP of a randomized matrix plz tell me. <- Please include ALL of the coding, you know it starts with: make matrix 1, .... etc.

thank you

I don't understand why you want to use get matrix height instead of get ground height ... it's maybe because you weren't positionning the camera a few meters/centimeters/feet/inchs/.. above the matrix
here's a code that work well

I'm very sorry to tell you guys that I keep shifting height as I walk :S very strange... but my height is not the height of the matrix... sugestions?

what code are you using? make sure you use update matrix afetr changing the height of your matrix!

I have a website!!!
So go there: http://www.freewebs.com/darkb/index.htm
on second thought you probably shouldn't

hide mouse

make matrix 1,200,200,10,10
randomize matrix 1,15
update matrix 1
load image "grass.bmp",1
prepare matrix texture 1,1,1,1

do
xrotate camera wrapvalue(camera angle x()+mousemovey())
yrotate camera wrapvalue(camera angle y()+mousemovex())

ox#=camera position x(0)
oy#=camera position y(0)
oz#=camera position z(0)
position camera 0,ox#,get ground height(1,ox#,oz#)/10+3,oz#

if upkey()=1 then move camera 0,0.1
if downkey()=1 then move camera 0,0.1
loop

This is the code I'm using... And I can understand you're getting mad (I for one am going to )

and this is the result after I compiled it:

When you run it, you'll see my point I hope...

Well, pretty simple to solve. Why the hell are you dividing height by 10?

Just get the height and add whatever height you want camera to be above matrix.

e.g. position camera 0,ox#,get ground height(1,ox#,oz#)+10,oz#

As you are using Camera 0, you must be using DB Pro.

Get Ground Height returns the height of the matrix at any given X and Z co-ordinate, whereas Get Matrix Height returns the height of the matrix at a given matrix tile intersection - that's why it asks for the matrix tile number.

To use Get Matrix Height, all you need to do is divide the current camera X and Z co-ordinates both by the matrix tile width and height - which in turn depends on the number of X & Z segments and matrix width and height used in the Make Matrix command when you created the matrix.

If you are using patch U5, there's a bug in it (now fixed for the final release) which returns a negative value for Get Ground Height.

If your character goes down instead of up when you reach a hill, you simply use the work-around:


Gh#=0-(get ground height(1,ox#,oz#)/10+3)
position camera 0,ox#,Gh#,oz#
