This is the one that i am trying to achieve. 1 it will get number of spawn ie AI that the user desired to spawn 2 speed of each spawn ie AI 3 desired time that the user want to finish. Do you have any recommendation for this ? Any tutorial will do

Hey there, when you press start you can run a delay node / timer with what you put in the desired time. Then run a for loop that goes from 1 to what you put in the first field. After you spawn cast the result to the type of the pawn you are spawning and set max walk speed from the character movement controller to the desired speed.
