Set a variable to the object you want to carry like obj_var_picked, then when your player is in collision with the object and a button is pressed like “Up arrow” check if the object variable is 0 so can be picked change the variable to 1 and set an action to check
Condition:
obj_var_picked = 1
player is in collision with object
Action:
Change the object position x to player.x
Cange the object position y to player y -16
Note: the -16 is in my case a half of the player height
This way the object always will follow your player.
So if you want to drop it add some event like if “Down key” pressed and object is in collision with player and object variable = 1
Do drop stuff…
