Here's a few ideas:
1. Utilize a formula to do the same thing as multiple events. As a simple example instead of doing this:
variable = 0
--- set variable to 1
else
--- set variable to 0
Do this:
every tick
--- set variable to 1-variable
2. Use functions if you are using the same thing in multiple spots.
3. Use third party plugins or make your own.
4. Make your own scripting language that you run using the 100 events and put the scripts in the instance variables of the objects.
