[Solved] map editor problem

[newbie123]

hello everyone

[Old Post]
i'm working on a map editor and i'm having trouble placing the image on the screen by clicking on the mouse.

what i want exactly is when you left click the mouse on the screen the image will get drawn in that position and stay in that position even if you click again.

My problem is that the image keep following the mouse coordinates instead of taking the last mouse coordinates and set it position there.

can you guys please help me i have been trying to fix this for 2 days and i had no luck.

sorry for being a noob

now i have an array of sprites and i want every time you click on the mouse a sprite will get drawn in that position.

i tried the following but the sprites get drawn on top of each other every time i click the mouse button

Code: [Select]


bool DrawMe=false;
int index=0;
while(window.IsOpened())
{
sf::Event Event;
while(window.GetEvent(Event))
{
if(Event.Type == sf::Event::MouseButtonPressed && Event.MouseButton.Button == sf::Mouse::Left)
{
index++;
DrawMe=true;
}
}

float MouseX = Game.GetInput().GetMouseX();
float MouseY = Game.GetInput().GetMouseY();

//Clear
window.Clear();

//Draw

if(DrawMe==true)
      {
 for(int i=0; i<=index; i++)
herosprite[i].SetPosition(MouseX,MouseY);
         DrawMe=false;
      }

for(int i=0; i<=index; i++)
window.Draw(herosprite[i]);

//Display
window.Display();
}
return 0;
}

Your program make the boolean always true when u click the first time!


U need to switch false drawme when the mouse bott are relased..



Sorry for my bad eng >.<

thankx that works.

but what if i have an array of sprites and i want to place every sprite in a different position when i click the mouse how can i do that ?

[newbie123]

i solveed it here is the code

Code: [Select]


      if(DrawMe==true)
      {
         towersprite.SetPosition(MouseX,MouseY);
        DrawMe=false;
      }
       window.Draw(towersprite);


but now i have an array of sprites and i want to place every sprite in a different position when i click the mouse any idea how to do that ?

the problem with this code is if i have an array of sprites and want to position them in different places that wouldn't work because every time you click on the mouse the sprite keep drawing on top of each other.

i dont know how to separate them

A map editor seems a little bit.. overkill for you, as in lot of cases, i think a resourcemanager would be in place here!

However, you'll need to store mapobjects/tiles somehow, a nice method is using std::vector<customclasshere>

Ill show you on how to do it using your methods but belive me, you should learn some basics first!

thank you very much it works perfectly.
i know that i'm a newbie but i'm learning as much as i can, i never used vectors but now i'll study the code carefully and try to understand it.
thank you again

See it as a dynamic array. A storage container for objects.

Code: [Select]

// Create a vector of floats
std::vector<float> Floats;
// Add a new float with value of 2.3
Floats.push_back(2.3);
// Add another float with value of 4.2
Floats.push_back(4.2);
// outputs 2.3
std::cout << Floats[0];
// outputs 4.2
std::cout << Floats[1]


this ofcourse works with all kind of types, classes, structs, enums andother objects.

EDIT: Btw the first code i posted shouldnt work perfectly, noticed some errors just now was very tired when i wrote it and its untested.
