My example, that didn't work:
public void Main()
{
string timerName = "Timer Block";
IMyTimerBlock TimerBlock;
List<IMyTimerBlock> TimerBlocks;
TimerBlock = GridTerminalSystem.GetBlockWithName(timerName) as IMyTimerBlock;
TimerBlock.GetActionWithName("Start").Apply(TimerBlock);

// var timerBlocks = new List<IMyTerminalBlock>();
// GridTerminalSystem.SearchBlocksOfName(timerName, timerBlocks);
// for (int i = 0; i < timerBlocks.Count; i++) {
// timerBlocks[i].GetActionWithName("Start").Apply(timerBlocks[i]);
// } }

Hi! How to find block by name? I have Projector blueprint, this blueprint have timer block, I need to start this timer when I run script. Probably is: on my ship I have another timers and timer, that spawn every new spawn add number (e.x. Timer Block 23, Timer Block 24 ...). Can you help me to find this timer with script?

The second screenshot shows the script, however I have updated the comments since I took that screenshot to be more noob-friendly.

Hum, how do i see the script?

Updated, I hope the new comments make sense!

Very useful. I was really strugging with that. You might consider adding more in depth comments, especially for the list making and using part.
