Collision with particles

fayt84

I have a particle actor named "Hammer" and it moves around dropping little hammers. The other actor in the scene is "OldMan". I am trying to get the oldman to destroy when a particle hits him. But it doesn't work I've tried a dozen things. Can you help me? I am a newbie to Gamesalad. Thanks

Particles cannot have rules and other actors cannot detect a collision with a particle.

You'll have to spawn the hammer actors instead of using a particles behavior.

I found the spawn actor behavior, but which rule, block or behavior do I use to #1 get it to drop randomly, #2 collide with actor? Thank you again

In the Spawn actor behavior you can enter random values for the x and y positions. Then in the hammer actor itself, make it move down or any direction you prefer.

Tried that and it displays giant images and doesn't move, the original smaller actor moves but that's it. Here is the screen shots: http://postimg.org/image/448rybtp9/ ..... http://postimg.org/image/hwn6tykgt/

The actor will spawn at whatever size the prototype is set to in the actors' inspector pane. Try changing the width and height there.

The Hammer actor needs a rule to move down, not the spawner actor. Also, it looks like you're spawning at x=1, y=100 instead of a random location.

All it does is sit in one place and doesn't move, but I guess it spawns at the right size, but it doesn't do anything. Also there are no options for "Random". Sorry to be a pain. http://postimg.org/image/vtqdu2dj3/

Okay I have figured some of it out, however spawn actor doesn't work and also move down (270 degrees) can't drop in random spots. I think we're almost there, anymore help? Thanks

"Watch out for the hammers, old man!"

In the From position boxes, you have 0 and 0, relative to actor. You need to click on the expression editor 'e' and enter a random expression such as (0,1024) and set it relative to scene.
