C++/SDL, Tic Tac Toe turn taking - c++

Question

Alright so I have this tic tac toe game I'm making with SDL and C++. I'm trying to implement AI into the game. I don't have a problem setting up the AI, but I have a problem making it where you can take turns. My problem is that when I make my move, I can just move as many times as I want before the AI moves. I want it so I can make my move, and I can't make my move again until the AI makes a move. No matter what I do it seems the turn taking doesn't work properly.
This is the class header
class Buttons
{
private:
SDL_Rect squares[8];
public:
Buttons();
void handle_input();
void load_Squares(SDL_Rect sqRects, SDL_Texture* squarTexs);
void show_Squares();
void AI_move();
int grid[9];
bool moveMade = true;
};
Here I check for mouse input, and depending on the location during the left button press, it sets the according grid value to equal 1, meaning it becomes displayed as a circle on the screen. I also make sure that the AI has made a move before it allows me to click.
void Buttons::handle_input()
{
double mouseX = 0, mouseY = 0;
if((event.type == SDL_MOUSEBUTTONDOWN))
{
//If left mouse button was clicked and AI has made a move
if(event.button.button == SDL_BUTTON_LEFT && moveMade == true)
{
//Get mouse location
mouseX = event.button.x;
mouseY = event.button.y;
//If mouse location is in particular square, set according grid value to 1
if((mouseX >= 0) && (mouseX < SCREEN_WIDTH / 3) && (mouseY >= 0) && (mouseY < SCREEN_HEIGHT / 3) && (grid[0] == 0))
{
grid[0] = 1;
moveMade = false;
}
//Basically does this for all other 9 grids
Here is my AI function, where I check to make sure the moveMade variable = false. Every time I make a move in the input function above, it sets moveMade to false, which means it should access this function, and only until it finishes this AI_move function should I be able to make a move again, because moveMade is set back equal to true.
void Buttons::AI_move()
{
if(moveMade == false)
{
AI_block(&moveMade);
AI_complete(&moveMade);
AI_rand(&moveMade);
moveMade = true;
}
}
Last is my show function, where I show a Circle(player) if the grid array value = 1, and I show the X(AI) if the grid value = 2.
void Buttons::show_Squares()
{
switch(grid[0])
{
case 1:
load_Squares(squares[0], circleTexture); break;
case 2:
load_Squares(squares[0], xTexture); break;
}
switch(grid[1])
{
//Does this all the way to grid[8]
}
Alright so my problem doesn't have to do with the AI dealing accordingly, as I haven't even set up my defense and offense functions. My problem is that I can make another move before the AI moves. Sorry if this is way too long, but if I could get any feedback on this that would be great.

Have you tried putting breakpoints at various points such as if(event.button.button == SDL_BUTTON_LEFT && moveMade == true) and then following the program through the see if moveMade ever actually gets changed to false?
You should also look at changing show_Squares() into a loop as there is a lot of repeated code using incremented indexes. Something like this:
void Buttons::show_Squares()
{
size_t array_size = sizeof(squares) / sizeof(int); //gets the number of elements in the array
for(size_t i = 0; i < array_size; i++)
{
switch(grid[i])
{
case 1:
load_Squares(squares[i], circleTexture); break;
case 2:
load_Squares(squares[i], xTexture); break;
}
}
}
