Ooops... Sorry... Can't call non const qualified functions on const objects....

General / [Solved] Cryptic error when trying to load texture from file
« on: February 14, 2018, 12:04:09 am »
Hey there,
When trying to load a font, compiler tells me:
This is the first error the compiler spits out.
By the way, I'm compiling for Android armeabi (Target) on Windows 10 (Host).
When trying to load a font, compiler tells me:
Code: [Select]
error: passing 'const sf::Texture' as 'this' argument of 'bool sf::Texture::loadFromFile(const string&, const IntRect&)' discards qualifiers [-fpermissive]Here's the offending code:if(!this->Start_Button_Texture.loadFromFile("StartBTN200x100.png", sf::IntRect(0, 0, 200, 100))){
//Err
}
//Err
}
This is the first error the compiler spits out.
By the way, I'm compiling for Android armeabi (Target) on Windows 10 (Host).

Well you see.... I do have the community edition... Guess I'll have to reinstall Visual Studio 
...
For the time being I got it to compile using the following steps:
Follow the Tutorial right up before the cmake step.
Follow the steps here just to compile cmake
Set the cmake path variable to the bin folder of the above step. If you want to use the examples then add the
Run the cmake step in the SFML-for-Android tutorial
Use
Go to [ndk-path-here]\source\sfml and add this line:
Now go to the android example folder and the example compilation steps on the tutorial page should work.
Result should be in android/bin/NativeActivity-debug.apk.
[PS. I did all of this in a separate partition, so I had to set a few environment variables myself.]

Hey there, I got past the step that requires 'Nsight Tegra VS Edition', by following the steps here: https://blogs.msdn.microsoft.com/vcblog/2015/12/15/support-for-android-cmake-projects-in-visual-studio/ and then setting my cmake path to the bin folder!

Hi there, I was trying to compile SFML following this link: https://github.com/SFML/SFML/wiki/Tutorial:-Building-SFML-for-Android
I installed all of the dependencies and then I rebooted my computer. I followed every step until I got to the cmake command. In this case I get this error:
But the problem is that this requires Visual studio Professional and I only have Express. What can I do?

CMAKE_SYSTEM_NAME is 'Android' but 'NVIDIA Nsight Tegra Visual Studio Edition'I looked it up and found out I had to install 'NVIDIA Nsight Tegra Visual Studio Edition' at https://developer.nvidia.com/nvidia-nsight-tegraBut the problem is that this requires Visual studio Professional and I only have Express
. What can I do?

Oh goodness how stupid I am....
I use an unused variable named count, and not the iterator index...
Wow...

I rewrote the update function to be more readable, here is the new code:
public void Update(Time Elapsed, Random R)
{
uint count = 0;
foreach(var b in m_particles)
{
var temp = m_vertices[count];
b.lifetime -= Elapsed;
if (b.lifetime <= Time.FromSeconds(0))
{
float Angle = ((R.Next() % 360) * 3.14159f) / 180;
float Speed = ((R.Next() % 50) + 50);
b.velocity = new Vector2f((float)Math.Cos(Angle) * Speed, (float)Math.Sin(Angle) * Speed);
b.lifetime = Time.FromMilliseconds((R.Next() % 2000) + 1000);
temp.Color = Color.White;
temp.Position = m_emitter;
}
temp.Position += b.velocity * Elapsed.AsSeconds();
float ratio = b.lifetime.AsSeconds() / m_lifetime.AsSeconds();
temp.Color.A =255;
m_vertices[count] = temp;
}
}
{
uint count = 0;
foreach(var b in m_particles)
{
var temp = m_vertices[count];
b.lifetime -= Elapsed;
if (b.lifetime <= Time.FromSeconds(0))
{
float Angle = ((R.Next() % 360) * 3.14159f) / 180;
float Speed = ((R.Next() % 50) + 50);
b.velocity = new Vector2f((float)Math.Cos(Angle) * Speed, (float)Math.Sin(Angle) * Speed);
b.lifetime = Time.FromMilliseconds((R.Next() % 2000) + 1000);
temp.Color = Color.White;

}
temp.Position += b.velocity * Elapsed.AsSeconds();
float ratio = b.lifetime.AsSeconds() / m_lifetime.AsSeconds();

Try this:
Make sure that the csfml binaries are included in your project and set to copy to output.
Also make sure that the csfml libraries are the same architecture as your sfmlnet binaries.

Ok, just tested, and found out that the alpha value goes from 255 to 0 in the first frame. Might it be because of the statement on line 97 because of ratio being to small?

Not sure, will have to test later in the day. Thanks.

I have taken the code from https://www.sfml-dev.org/tutorials/2.4/graphics-vertex-array.php at the bottom of the page and translated it into its C# equivalent, but I can't seem to find the error; it doesn't output anything to the screen, and it is just black (The screen clear is black). https://pastebin.com/pF40bKaA is where I have pasted my code.
I am sorry for any stupid mistakes I made in the "translation" as though I know basically nothing about C++ in specific. Thanks!
