Hi Everybody

First post

Im working my way through the said tutorial and I am getting a runtime error on the Intoduction to Matrix commands

+ Code Snippet

rem place random texture on each matrix tile
for x = 0 to 19
 	for z = 0 to 19
	 	t = Rnd(3)+1
			
			 Set Matrix Tile 1,x,z,2
	 next z
next x

At this point I get a runtime error of Matrix tile does not exist

I bet im doing something really noobish. But any help will be appreciated

Thanks

Brett

do you have a "create matrix 1,100,100,20,20" or something like that in your code somewhere near the start?, you have to create one before you texture it, and it has to be the right size in tiles or you will get that error, you also need to create a matrix texture, then make sure you don`t use more texture tiles than you made when you made the texture etc, computers are realy dumb...just cos you mentioned a matrix doesn`t mean the `puter will think to make one, you have to specificaly tell it to make one first, I think maybe you should read some more of the tutorial, you may have missed something (never seen it myself..so just guessing here), basic rules tho

make a matrix
make a texture of x tiles
make sure the x,y and tile numbers are within bounds
apply textures to the different tiles on the matrix
update the matrix so you can see the changes you have made to it

and it should work just fine.

Yeah ive created it the whole of my code is :

+ Code Snippet

rem turns the sync rate on
Sync on
Sync Rate 30


rem create matrix
make matrix 1,10000,10000,20,20

rem texture matrix

load image "floor1.bmp",1

prepare matrix texture 1,1,1,1

rem randomize the matrix

randomize matrix 1,250




rem place random texture on each matrix tile
for x = 0 to 19
 	for z = 0 to 19
	 	t = Rnd(3)+1
			
			 Set Matrix Tile 1,x,z,2
	 next z
next x

rem update the changes to the matrix
update matrix 1

rem loop calling the object until F12 is pressed
Do 
	
	
	Rem Control Input for camera
	If Upkey()=1 then Move camera 10
	
	
	if leftkey()=1 then Yrotate Camera Wrapvalue(cameraAngleY#-5)
	if rightkey()=1 then Yrotate Camera Wrapvalue(cameraAngleY#+5)
	
	if spacekey()=1 
		Fill matrix 1,Rnd(50),Rnd(3)+1
		Randomize matrix 1,250
	Endif

	x#= Camera position x()
	z#= Camera position z()
	position camera x#,250,z#
	
	rem refresh screen
	Sync
Loop

rem end of program

Ive gone through it with a fine tooth comb, maybe it doesnt like the bmp im trying to load cos im using the demo version atm and picked up a .bmp thats called floor1 that i found in the help files and dropped into the current working directory. It could be the wrong size compared to the grass.bmp i should be using i suppose.

there is only one tile, so you can`t use

set matrix tile 1,x,z,2<<<you asked for tile 2

since

prepare matrix texture 1,1,1,1

make just 1 texture tile (1x1)

so alter the command to read

set matrix tile 1,x,z,1

and all should be well, cheers.

Opps again I refer to my previous statement

Im a nOOb

the line should read

prepare matrix texture 1,1,2,2 <<<I changed this messing around, this takes a tile and splits it into 4 quadrants.

the other line should read

Set Matrix Tile 1,x,z,t

but I did try what you suggested and still getting the error

LOL im such a nOOb.
I solved the problem. I saved a newversion of the tutorial in a different directory. So it couldnt find the tile.

Thanks for the help
