Now, before anyone asks me to use the search button, I just wanted to say I have... numerous times. I have tried sparkys collision, but most of the tutorials I find make a matrix,whereas I load a mesh, and I don't get how to connect those two objects (the main object I control and the level) into colliding into each other.

Also, I was just wondering if Sparky's Collision comes with gravity codes as well.

(btw, I have looked at the tutorials in Sparky's Collision, with no luck.)

Here is ALL of my code
(I know its not the best)

+ Code Snippet

Sync on
Sync rate 60
backdrop on 
set display mode 800,600,32
hide mouse

load music "soundtrack1.mp3" ,1 
Play music 1

load object "Twitch_2.x" ,1
position object 1,0,0.5,0
rotate object 1,0,180,0
scale object 1,30,30,30

load object "level_alpha.x" ,2
position object 2,2,0,0
scale object 2,150,150,150  

do
   
   if keystate(17) = 1 then move object 1,-0.07
   if keystate(30) = 1 then y=wrapvalue(y-1)
   if keystate(31) = 1 then move object 1,0.1
   if keystate(32) = 1 then y=wrapvalue(y+1)
   
   yrotate object 1,y
   
   set camera to follow 0, object position x (1), object position y (1), object position z (1), object angle y(1)-180, 2, 1.5, 25, 0


sync
loop

do
sync
loop

So if anyone can help me that would be very much appreciated

If anyone cares this is how the game looks:

Hi Sazex. Sparky's comes with several examples, and one of them is a first person/3d person, and it has gravity and you can easily put your map in it. Of course, you will have to scale you level to fit the size collision. Sparky is free, download it and if you have any problem we can help you.

Cheers.

Sort of on topic... how complete is sparkys? and how does it compare to Dark Physics?

@ chafari, ok so I tried what you said, and took another spin on the examples that came with SparkysCollision, but unfortunately did not help me at all

Though I did look online for some more tutorials and thought I'd give one another try, and it yielded some results, though, not what I expected or want.

Whenever I try to move the object, from another position than its starting position, it just falls through the ground, or flies straight up.

here is my code if you know what I am doing wrong:

@MrValentine, well I do not have DARKphysics, so I can not say, but if you want, you can try out Sparky'sCollision for yourself, here is the link:

To go along with chafari's code...
It would be a good idea to spend a day or so and get comfortable with creating your own UDTs (user defined types). When you use these, you can compartmentalize values that are specific to each thing and reduce the amount of code that you use. For something specific and quick, they are not that important...but when you have hundreds of different types of objects (players, enemies, bullets, health pickups, world clutter, etc.), setting each to a udt is almost essential to keep things organized.

@chafari wow thanks! It did the trick, but for some reason the character is still floating over the land, though he is colliding with the buildings

so many thanks for that... but if you know why he is floating over the map that would be awesome
here is a pic:

Perhaps you need to scale your level a bit biger, or your character a little bit smaller. Can you send me your level and Character to test

No that's not the problem. Your character's center point is located at it's feet, and that's also the point where you perform a sphere cast. This means the character will be offset from the ground by the radius of the sphere cast. Untested, but this should fix it:

Thank you so much Comet, it did the trick! I now have my character correctly colliding with the floor and the buildings!

The SET CAMERA TO FOLLOW command has a special flag to have this situation automatically handled.

From DBPro help:

Quote: "SET CAMERA TO FOLLOW

This command automatically controls the camera to provide a tracking system. By providing the 3D world coordinate of the entity you wish to
track, and some camera data, your camera will automatically update its current position each time this command is called. The X, Y, Z and
Angle values provide the coordinate to track. The Distance value specifies the required distance between the coordinate and the camera. The
Height value specifies the required height of the camera in 3D space. The Smooth value specifies the level of smoothing required for the
camera, where a value of 1.0 is no smoothing and a value of 100.0 is lots of smoothing. The Collision value is a special flag that allows the
camera to detect whether it is hitting any of the static collision boxes and if set to one will automatically adjust so as not to enter these
collidable areas."

Hi, theSPACEmafia.

Have a look at TDK's turtorials:

http://forum.thegamecreators.com/?m=forum_view&t=99497&b=10

Tutorial 10 "Dark Basic Collision Made Simple" is probably what you want.

Also, you might want to make the controlled cube a little bit smaller than the cubes used for the maze so that it's not constantly touching the walls. This could cause problems when you come to use the collision commands.
