How do I make a progress bar to show how much of my game has loaded?
It would be nice to have a text displaying the object currently being loaded as well as a graphical bar.

ok- to have the loadscreen say the object being loaded:

+ Code Snippet

print "Loading car"
load object "car.x",1
print "car loaded"

www.tinnedhead.tk watch this space for the first ever calculator to show the working out. also look out for our first game- ww.exor-mk1.tk

just make a box using the BOX command and make it bigger everytime something is laoded

. example:

+ Code Snippet

box 0,0,0,20
load object "bla.x",1
box 0,0,20,20
load object "something.x",2
box 0,0,40,20

Specs: AMD Athlon 1800, 256 DDRRam 266mhz, 80GB HD 7200rmp U133, Geforce 4 Ti4400 128mb

Gjl,

Here is what you have to do. First you have to know how many objects you need to load. Then you have to know how many objects are loaded. That gives you your first first set of variables.

TotalObjects# = 1000
TotalObjectsLoaded# = 123

Now you get the percentage of TotalObjectsLoaded which is
TotalObjectsLoaded# / TotalObjects#

That gives us our third variable.

TotalObjectsPercent# = TotalObjectsLoaded# / TotalObjects#

The reason you convert it to a percent is because that is is all a bargraph shows is a percentage of something.

Now to draw the actual bar graph.

These here are the basic variables to draw the actual Box

`Defines the upper lefthand corner of the box
`Adjust these two numbers to change the location of where
` your Graph shows up on the screen
BarX# = 100
BarY# = 100
`Defines the height and length of the box
Barlength# = 100
Barheight# = 10

Okay, so how do we adjust the size of the bar to represent the size the box should be? Simple

`How much of the bar to fill
Barfill# = Barlength# * TotalObjectsPercent#

`draws your graph
box BarX#, BarY#, BarX# + Barfill#, boxY# + Barheight#
`This line represents 100% box filled
line BarX#, Bary#, BarX# + Barlength#, bary# + barheight#

Snippet one is Just the Basics to draw the bar

+ Code Snippet

set display mode 1024, 768, 32
ink 255,255

TotalObjects# = 1000
TotalObjectsLoaded# = 123

TotalObjectsPercent# = TotalObjectsLoaded# / TotalObjects#

BarX# = 100
BarY# = 100

Barlength# = 100
Barheight# = 10

Barfill# = Barlength# * TotalObjectsPercent#

box BarX#, BarY#, BarX# + Barfill#, barY# + Barheight#

line BarX# + BarLength#, BarY#, BarX# + barlength#, BarY# + barheight#



wait key

Code Two Allows you to resize the bar using the Left and right Arrow Keys...

+ Code Snippet

set display mode 1024, 768, 32



TotalObjects# = 1000
TotalObjectsLoaded# = 423

TotalObjectsPercent# = TotalObjectsLoaded# / TotalObjects#

BarX# = 200
BarY# = 100

Barlength# = 100
Barheight# = 10




do
cls



TotalObjectsPercent# = TotalObjectsLoaded# / TotalObjects#
Barfill# = Barlength# * TotalObjectsPercent#
box BarX#, BarY#, BarX# + barfill#, barY# + Barheight#

line BarX# + BarLength#, BarY#, BarX# + Barlength#, bary# + barheight#

if rightkey() = 1 and TotalObjectsLoaded# < TotalObjects#
   inc TotalObjectsLoaded#
endif

if leftkey() = 1 and TotalObjectsLoaded# > 0
   dec TotalObjectsLoaded#
endif



loop

Ok I'm guessing this would work out:

+ Code Snippet


loadtotal=3
load object "a.x",1
loading$="a.x"
loaded=loaded+1
gosub _loadinginfo:
load object "b.x",2
loading$="b.x"
loaded=loaded+1
gosub _loadinginfo:
load object "c.x",3
loading$="c.x"
loaded=loaded+1
gosub _loadinginfo:



_loadinginfo:
percentloaded#=loaded/loadtotal

BarX# = 100
BarY# = 100

Barlength# = 500
Barheight# = 10

Barfill# = Barlength# * TotalObjectsPercent#
print "Loading " + loading$ + "          " + loaded + "/" + loadtotal
box BarX#, BarY#, BarX# + Barfill#, barY# + Barheight#

line BarX# + BarLength#, BarY#, BarX# + barlength#, BarY# + barheight#
return

That would work, but you need to change this line

Barfill# = Barlength# * TotalObjectsPercent#

to

Barfill# = Barlength# * percentloaded#

As for the way you are loading them I'm going to make a quick suggestion I would actually save the object information to a file, or at least use data statements...

+ Code Snippet

loadtotal = read a

for j = 1 to a
   read b$
   load object b$,1
   loading$=b$
   loaded=loaded+1
   gosub _loadinginfo
next j


_loadinginfo:
percentloaded#=loaded#/loadtotal#

BarX# = 100
BarY# = 100

Barlength# = 500
Barheight# = 10

Barfill# = Barlength# * percentloaded#
print "Loading " + loading$ + "          " + loaded + "/" + loadtotal
box BarX#, BarY#, BarX# + Barfill#, barY# + Barheight#

line BarX# + BarLength#, BarY#, BarX# + barlength#, BarY# + barheight#
return







data 3
data "a.x"
data "b.x"
data "c.x"

Hope that helps. There is a lot of differant ways you can go about doing things.

If I was you, I wouldn't hardcode that kind of thing. I would save information like that in an external file to your engine. That way you can build your engine up, then add stuff later view your external files. If you hardcode your game it makes it harder to reuse your code in other projects.

Ralen's suggestion is a good one... if you make a simple file that includes what files to load, you can put your entire load system into a convenient loop!

[PSEUDO CODE]

open file "stufftoload.txt"
read from file "num_of_files_to_load

for i=1 to num_of_files_to_load
read from file filename$
load object filename$,i
update your loadbar here!
next i

[/PSEUDO CODE]

of course you might want more detailed information in your load file, but I think that's the general idea!

Thanks for that! Although I'm not sure what exactly I should include in the file ie. how it should be laid out. Also what does the b$ string do in Ralen's code?

Its part of the data statements at the bottem.

It reads a string from one of the file names at the bottom and puts it in the b$
