我需要在计时器滴答内的按钮单击对象上使用if语句？

Question

Basically in the code below where i highlight, i would like to know how to use drawBricks method in the timer tick when that button(btnDisplayBricks) is pressed. Because i am using a timer tick and picturebox for paper drawings etc i cannot just simply call the method from within the button click event because the paper then clears in the timer only allowing me to display the bricks before timer1 starts any ideas.

private void timer1_Tick(object sender, EventArgs e)
    {
        paper.Clear(Color.LightSteelBlue);

        DrawBall();

        MoveBall();

        DrawBat(paper);

        if (btnDisplayBricks_Click[0] = true)               ///code here problem

        //then call method
            DrawBricks(paper);




    private void btnDisplayBricks_Click(object sender, EventArgs e)
    {
        DrawBricks(paper);
    }

}

}

Answer 1

problem is in your equation, you should use == instead of =

if (btnDisplayBricks_Click[0] == true) 

also move methodbtnDisplayBricks_Click outside of timer1_Tick

private bool buttonClicked = false;

private void timer1_Tick(object sender, EventArgs e)
{
    paper.Clear(Color.LightSteelBlue);
    DrawBall();
    MoveBall();
    DrawBat(paper);

    if (buttonClicked)
    {
        DrawBricks(paper);
        // maybe you want to set buttonclicked to false again, but specs are not clear to me
        // buttonClicked = false;
    }
}

private void btnDisplayBricks_Click(object sender, EventArgs e)
{
    DrawBricks(paper);
    buttonClicked = true;
}
