spawnPoint
Using the Spawn Actor Of Class node on Event Begin Play , I was able to spawn en-
emies. However, to ensure that it is random and lasts for a while, I set a random value to
the RandomValue variable and based on the resulting value, I pick whether to spawn a red
or green enemy.
To ensure that it is sort of a loop, I decided to use a new approach, which is the Timeline
node. This node controls a value over time. I set its time in its graph to 1.5 seconds, and
never cared about the resulting value as I won't be using it, I just made use of the animation
duration and forced it to run every time an enemy finishes spawning. With this, I get the
following sequence:
1. Execute the timeline node.
2. The node finishes running.
3. Randomize the value of the integer.
4. Select an enemy type.
5. Spawn the enemy.
6. Run the timeline node.
