What code should I use to make an pickup object “when player hit obj, obj is removed and score is +10”
I have tried this found in the Help content
function bounce_event()
{
if (event_type == EVENT_IMPACT)
{
ent_playsound(my,explode,50);
ptr_remove(me); // disappear when hit
}
}

action exploding_barrel()
{
my.ENABLE_IMPACT = ON; // sensible for push collision
my.emask |= ENABLE_IMPACT;
my.event = bounce_event;
...
}
but nothing happened and tired other ways but still no luck. Do they need to both be in void main if so they crash when its ran.

You have to apply the action to an entity, that one that you want to be picked up.
You can hit F11 twice when running the level to see the collision boxes of player and entity and whether they actually touch each other.

There's been a thread about this some time ago in the beginners(Starting with GameStudio) forum, but it was in German.
Maybe, you can understand at least the code.

Thank you that is what it was was the bbox my object did not have one. Any how thank you agine for you time.
