Help ! Can't shoot enemies on Vert.Shooter game

I made my own version of Space Blaster.

But I have a problem when I tried to shoot lasers to enemies. That lasers just like move trough the enemies. but when I get hit with their bullet, I take some damages. When the spaceship is on collison with a enemy, it also take some damages.

.

whereas all of them are in the same layer, and I think I did exactly like the examples.

.

What is my mistake at this point?

I not quite understand what is wrong with what you want to do?

if you don't want to take damage from bullets or colliding with the enemy?

Look at your events and make sure you have an event for when your lasers/bullets collide with the enemy, then destroy the enemy. It is hard to get much more detailed than that without seeing your event sheet.

please take a look at my screenshoots

the problem is, I can't shoot enemies. but they can shoot me.

can you post capx of your project

You are probably missing a simple event like:

laser on collision with enemy - enemy destroy

but without seeing your capx or eventsheet we can't be sure.

1) check your collisions events

2) check all your boundary boxes on all your sprites, if you fiddle with spites sometimes it gets all messy.

what is wrong with boundary boxes?

did you look at my screenshoots? which one is the problem?

It might be the collision poly of either the laser or the enemies. Are you using square boxes with the animations stuck to your objects or are you using the animations directly for collisions?

i changed the laser with red (i use the blue one before). and that problem is gone.

thats weird ._.
