Hey guyz. I aint that new to darkbasic but how u make a loading bar?
My game (The SAS Elite which is a fps) contains a load of objects and takes some secons to load. How can I create a loading bar to show when all the objects are loaded?

Well as far as I kinow you can't update the bar say half way through loading an object but if you say it contains aload of objects you can update the bar after each object. To find out how much to update it you could say find out what % of the total bytes to load the object took up and then add that to a variable of total % of bytes...

O ok. Well I gotta another issue. Yes the most bliddy hardest thing to programme - OBJECT COLLISION . I kinda figured out how to use it because I made a wall but I cant figure out the coordinates for most things.
Here is the code I used to make a wall.
Thats only the function. Theres some other stuff but this is just an example.

Function DecoCollide(X#,Y#,Z#)

for u = 1 to 1
for v = 1 to 1
if X#>u*10000-10000
if X#<u*10000+110
if Z#>v*10000-110
if Z#<v*10000+110
if Y# < Get ground height(1,u*5000,v*10000)+575
Collide=1
Exitfunction Collide
endif
endif
endif
endif
endif
next v
next u
Collide=0

Endfunction Collide

I'm quite sure there is an Object Collision command where it checks for collision with another object. [Commands: Object Hit and Object Collision] And if you would like to check for collision with a wall. I'd make sure that objects 1-200 [Or whatever] are walls and then do...



The code might not work but it should give you an idea.

Well I'll give it a shot. You see, the code I typed originally worked but when I tried to copy the function and call it DecoCollide2 or whatever - it didn't detect. By the way, what is playerobject?

Are you sure that code works? Don't forget, Im using DarkBASIC Classic not DarkBASIC PRO!

okay, there are a few major problems with what your doing here. firstly, the code you're using for your collision (DecoCollide?!) is strangely reminiscient of the code in the monster hunt tutorials. its great that you're using the tuts, but it appears you don't really know what you're doing. firstly, using object collision is an easy solution. the problem is that it has a tendency to be unbearably slow. i prefer math collision.
let me back up a minute. the reason you have trouble positioning stuff is that when you place something in coordinate space, the origin for an object is the center of the object, so if you put a cube in space that's 10 units across and want it's bottom corner at 0,0,0, you need to position it at 5,5,5 for the corner to be at 0,0,0.
where was I? okay, so, for math collision, say you have a plain that's 100 units across and 50 units tall for your wall. it's positioned at 50,25,100, so it's sitting on the floor with one edge at x = 0, 100 units from the origin on the z-axis. to check for collision, just set up some if statements. for example
IF objectz# >= 98 and <= 102
IF objectx# >= 0 and object x# <= 100
you hit the wall!
ENDIF

I never knew you were using DBC, and I dont know whether it would work in DBP or DBC.

Dont worry now. I have figured out what the monster tut code means. I also figured that for object collision, you can fit it all in function DecoCollide (It means Decrease Collide because DECO means DECREASE). Thanks for your help anyway. At least your code gave me a taste of MATH COLLISION.
Thanks again,
Nick Rakosi
PS. I will need your help in future!
