How do I make player pick up object and shoot picked object?

Hello can someone help me to sort out problem pls.

My player is able to pick up object with

player grab_instance 0

-on collision with box

-set posistion to player with box

than

-box pin pin to player

add 1 to grab_instance

if value grab_instance 1 and A pressed

- player subtrace 1 from grab_instance

- box set bullet speed 300

- box pin unpin

problem is cos all of the boxes getting bullet speed 300 i want to release just box picked by player all of rest of boxes need to stay on possition

is any way to do it thank you for all help and sorry for my english

i can pick up and shoot box just once sometimes system allow me to pick up second time but cant shoot

Why the second event "Keyboard A is down" is nested under the firs event? You need to move it to the top level!

Also, add that condition I posted in my previous comment to only pick the pinned box when shooting it.

all working thank you a lot for help

i have diff question can you tell me why player is falling down throut platforms if behavior is jump thru and is all good when platform is solid. player is falling through when walking on them but good if platform is solid.

agein thank you for your help :))))

Jump thru behavior is buggy. Check the collision polygon, make sure that the platform angle is 0 degrees.
