littlr combo you can make: put in a blueprint dynamic motion then add gravity- but on off.
step 2:
Go to rules
"When this is tapped"
Then find a response named modify a behavior.
Then tap on it then tap on it again (not to add other code, Just to tap the code he is on) check until you find Y Velocity Dynamic then tap on it put the value on -1 then add a new code "enable behavior" make it enable the gravity.
