This is an example of loading a map from a fps creator into an app game kit.
Did I write everything correctly?

The code doesn't work for some reason.
Although it worked in the examples.

programming is a hobby, not a job.
P.S. in google and youtube - nikename pavelman- it is not me!

if it works in the examples and not in your project then the code is good, check the file paths

and please, don't spam my inbox with your help requests, all it will achieve is make me ignore you!

Edit: in future, if you want help via PM send the project, not a wall of unformatted text

The program gave an error when going to the list of meshes of the main mesh. I suppose this is due to a glitch in determining the number of meshes of the main mesh.
After all, I compiled the simplest game in fps creator and used your program to convert the map.
I just haven't dealt with objects like object before so I have no idea. how it actually works.
Checked in dark basic pro. Everything works.
It automatically applies all textures. he does not need this code.
I added comments to the code.
Correct me if I was wrong. Thanks.

Not my program, Not my code.

That code *looks* ok to me, I see no obvious errors the fault must be the model

LoadObjectWithChildren expects a animated object, the meshes are children of the armature, try with LoadObject

add:

Log(Str(GetObjectNumMeshes(WorldObjectID))) 
Log(Str(GetObjectNumChildren(WorldObjectID)))

and run in debug >> if you get 0, there is your problem

code from DLC Shader pack

From here this code.
I cut off the special effects that are premium to him.
Left only loading the textures themselves. And that's all. the code doesn't work. Can you help me figure out the part of the code that loads and textures the map?
Please.

Quote: "the code doesn't work."

That's very vague, what does not work, exactly?

I just ran a test here

The untextured part uses illumination maps which you saw I commented out, to use this you need to use the shaders

Now swing the magic wand.
Have you tried to put your card there?
For example, made in FPS creator,
And converted with a welder?

Expelliarmus!! ....

Many Confucius quotes are running through my head right now!

I do not have FPSC or the welder installed, sorry, you still have not said what is not working, I think I need a magic wand trying to solve your problem!!

upload your project to dropbox [or other reputable file sharing site] and PM me a link I will take a look but I am not installing a bunch of stuff just to answer a question

For one thing shouldn't the length of the array be set to 0 not -1 as setting to -1 will cause an issue when accessing the materials array.

It seems to have worked out, but the last texture for some reason does not want to dress.

a quick guess at a glance:

try removing the -1 from:

function SetObjectMaterials(WorldObjectID)
for MeshID=1 to GetObjectNumMeshes(WorldObjectID)-1

Also wrong texturing....

But this is in principle decisive.
You can change the names of the textures in the substitution mode and leave them when they coincide with the original.
But it’s hard.

That error suggests to me that you have more meshes in the object than you think.
It would also explain why one of the textures is not showing

The texture of the last mesh is not displayed.
But why are textures overlaid on their own? Unclear
That is, the textures are generally not applied quite correctly.
The map was made in FPS creator.
With the help of a tool provided by a kind user, I processed the map. And made a readable file. [file.x]
I converted the textures to a readable format. [file.png]
It seems that everything worked out, but ... It looks like we will have to start renaming textures. But they are superimposed according to their rooms.

Thank you. I checked the object again.
It loads into dark basic pro without errors.
In the app game kit with errors.
It is necessary to look for an error in the code.
Or, using the substitution method, rename the texture files.

This means that the error is not in your program.
