Question

I’m currently stuck on making the title screen to a game I’ve been planning.

The form loads and TMRopI (a timer) starts ticking, Increasing the opacity of the form, creating a fade in effect, and revealing a logo on the form. every time the timer ticks, an integer increases by 1 (or at least it’s supposed to). A picturebox should become visible after the integer reaches 150 (the form is at full opacity when the integer equals 100) creating a pause before the picture is changed. The only problem is, it seems to be comepleteley ignoring my integer.

private: System::Void Form1_Load(System::Object^  sender, System::EventArgs^  e) {

             TMRopI->Enabled=true;
         }
private: System::Void TMRopI_Tick(System::Object^  sender, System::EventArgs^  e) {

             int num=0;
             num+=1;
             this->Opacity+=0.01;

             if (num >= 150)
                 PBXtitle->Visible=true;
         }

Another option is to change the definition of num to static. However, making num a member variable of the class is the more C++ way to do it.

static int num=0;
num+=1;
this->Opacity+=0.01;

if (num >= 150)
    PBXtitle->Visible=true;

This way, num gets set to 0 on the first call to the function and it’s value is saved between subsequent calls.
