I have decided that it would be good to make a adventure game as my first game. This would included a character which walks around a landscape doing missions and quests. However I thought this was a bit to complexed for my first game, so i thought it would be a good idea to start by making the character walk around a landscape and them see what happen if i get that far. I have read the DB manual and one of the 'task for you do'(or what ever its called)is to make a 3D character walk around a matrix. I have no idea how to achieve this and was wondering if somebody could help explain how i would go about doing it or if somebody could help me through the first few steps.

I am a total newbie, well i've done the pong tut and looked at the monster hunt and limit rush tuts. I have also little(but some) experience of modeling and making landscapes so i will probably be using the DB media and a randomised matrix(if that helps).

I'm am also usind DB.
Thanks for your time

Here is some simple code I wrote up just now:

+ Code Snippet

` normal things
sync on

hide mouse

` make player object
make object sphere 1,5

` set up matrix
make matrix 1,100,100,10,10
randomize matrix 1,3

` position camera and point it
position camera -50,40,30
point camera 50,0,50

` position player object in middle of matrix
position object 1,50,get ground height(1,50,50),50

` begin main loop
do

` use arrow keys to move object
if upkey()=1 then move object 1,1
if downkey()=1 then move object 1,-1
if leftkey()=1 then turn object left 1,5
if rightkey()=1 then turn object right 1,5

` get player object position
x#=object position x(1)
z#=object position z(1)

` position player object on matrix
position object 1,x#,get ground height(1,x#,z#)+5,z#

` update screen
sync

` go back to beggining of main loop
loop

That will make a matrix and let you move a sphere around on it. Study it and play around with the different parameters for the commands and see where it takes you.

Just stick to it and you'll get it easily enough.

Thanks Durdge39 I have managed to get the character from the tutorial to walk around a randomized matrix. But i don't really want to use that model, if you just change the name of the model in the LOAD OBJECT "idle.x",1 will this change the model over and will it work or do i need to change some of the parameters.

Here is what I have done so far.

rem make matrix
make matrix 1,1000,1000,10,10
randomize matrix 1,50

rem Load 3D object and append walking data to it
LOAD OBJECT "idle.x",1 : APPEND OBJECT "walk.x",1,100
YROTATE OBJECT 1,180 : FIX OBJECT PIVOT 1

rem Loop 3D object animation from 0 to 20 (idle)
LOOP OBJECT 1,0,20 : SET OBJECT SPEED 1,10

rem Activate manual syncronization
SYNC ON

rem Begin loop
DO

rem Modify character angle based on left/right keys
stage=0
IF LEFTKEY()=1 THEN a#=a#-8.0
IF RIGHTKEY()=1 THEN a#=a#+8.0
a#=wrapvalue(a#)

rem Modify character position based on up/down keys
IF UPKEY()=1 THEN x#=NEWXVALUE(x#,a#,3) : z#=NEWZVALUE(z#,a#,3) : stage=1
IF DOWNKEY()=1 THEN x#=NEWXVALUE(x#,a#,-3) : z#=NEWZVALUE(z#,a#,-3) : stage=1

rem If character action changes
IF stage<>oldstage
	IF stage=0
		SET OBJECT FRAME 1,0.0
		LOOP OBJECT 1,0,20
		SET OBJECT SPEED 1,10
	ENDIF
	IF stage=1
		SET OBJECT FRAME 1,105.0
		LOOP OBJECT 1,105,125
		SET OBJECT SPEED 1,40
	ENDIF
	oldstage=stage
ENDIF

rem Update character position and angle
POSITION OBJECT 1,x#,get ground height(1,x#,z#)+5,z#

YROTATE OBJECT 1,a#
rem Position camera off center
POSITION CAMERA x#,y#+100,z#-150

rem Refresh screen
SYNC

rem End loop
LOOP

+ Code Snippet

rem make matrix
make matrix 1,1000,1000,10,10
randomize matrix 1,50

rem Load 3D object and append walking data to it
LOAD OBJECT "idle.x",1 : APPEND OBJECT "walk.x",1,100
YROTATE OBJECT 1,180 : FIX OBJECT PIVOT 1

rem Loop 3D object animation from 0 to 20 (idle)

rem If character action changes

	IF stage=0
		SET OBJECT FRAME 1,0.0
		LOOP OBJECT 1,0,20
		SET OBJECT SPEED 1,10
	ENDIF
	IF stage=1
		SET OBJECT FRAME 1,105.0
		LOOP OBJECT 1,105,125
		SET OBJECT SPEED 1,40
	ENDIF
	oldstage=stage
ENDIF

Thats looking good. Along with changing the filename make sure that you have the object in the same folder as your source code. The thing with having a different object is you will have to change all of the frame parameters and such for the animation commands or they will not function properly and you will have a jumbled mess on your hands.

The parameters that you will need to change will be the ones below:

append object - start frame (2nd parameter)
loop object - starts and end frame (2nd and 3rd parameter respectively)
set object speed - speed value (2nd parameter - this is personal taste)
set object frame - frame number (2nd parameter)

What you need to set these to depends on your object, I can't tell you this because I am unable to do 3d animating or use the tools to do so. If you post your object in the 3d discussion board someone will probably be able to help you. If I've missed anything let me know.

If I were you and you were me, then you'd be yourself 'cos you are me and I am you.

i have managed to change the model in the game by just fiddling around with the parameters but i what to make the character attack when i press spacebar

im not sure how to do this could someone please have a look at my code and tell me how i should do it

see this is where i get confused... where do you load the character and show a animation?

i have now manged to make the character attack when you press spacebar but to be honest its not really a game yet so i am going to try to and stop the character going outside of the matrix. I thought i could do this by putting boxs around the matrix, hiding them then using some sliding collision or something. Is there a better way of doing this that will save time

.

I'm then going to get or make a model of a dragon and then get it to try and kill the man and you(the man) have to kill the dragon.
IF anyone has any animated models of dragons they would be very handy.

I have looked at the monster hunt tut but i can't get the goblin(it was going to be dragon but i don't have an animated model and i'm pants at modelling) to come after the character and then try and kill him. Could somebody help me with the AI i will have another go at it today and also look in the code snippets but if someone explained it to me i would know what i was doing.

Thanks
