Trying to create timed events. I'm new at this.

Hello,

I hope that someone can help me out. I’m pretty new at all of this, and I’m having trouble getting my enemy types to spawn at a specified time. I’m turning on what I’m calling “Phases” by referencing my in game timer, and using “if (ScoreTimer.Current == “00:10”)” The problem I’m having, is when I try to call the same “if” command a second time, it no longer works. I am new to Java Script and coding, so I’m assuming that there’s something I’m missing, where I cant use the same command twice within the Update Function. Can anyone help out? Sorry for the large script.

For me, when doing timer events and such, I always keep the timer value as a float, and simply check if it’s under said value, then increase on the phase value. For example…

float timer = 10.0f;
int phase = 1;

//more useful coding stuff here

switch(phase)
{
case 1:
    if(timer <= 5)
    {
        //spawn, create, etc. Your coroutine has this covered, so no worries!
        phase++;
    }
    break;
case 2:
    if(timer <= 2)
    {
        //spawn, create, etc. Your coroutine has this covered, so no worries!
        phase++;
    }
    break;
}
