Here are the basics, but the best way to learn is to try them out for yourself.
On Activate:
On activate is a type of way to make events happen. (An Input event) Basically this makes it so once you click on the brick, the event will occur.
Dissapear:
Dissapear makes bricks invisible and walk throughable for a set time. the box with "5" already marked sets how long the brick will stay invisible. setting it to -1 makes it invisible forever, setting it to 0 makes it instantly visible.
The X, Y, and Z axis':
For some of the events to work, you must understand a 3d coordinate graph. (Or just figure out that they are directions, either way.) No matter what, Z (The 3rd box) will always go up and down. Use negative values to go down, and positive values to go up. The X and Y vales go left and right, forward and back. (X is the first box Y is the second.)
Spawn Projectile:
Spawn projectile will make a bullet shoot out of the brick! Select what kind of projectile you want it to shoot, then use the 3 boxes on the left to choose it's direction and how fast it goes. If you want the bullets to have some variation in accuracy, use the boxes on the right to set how much of a difference you want there to be. (Note: I'm not sure what the difference between positive and negative values in these boxes is.)
Set Velocity:
You can use set velocity to make players shoot in a direction! Set the direction you want them to go using the boxes, and then it should work. Similar to spawn projectile.
On Player Touch:
Similar to on activate, this is an input event. When a player touches the brick, the event will happen.
Relays:
Relays can be confusing. However, once you get the hang of it they are easy. Relays are used mainly for repeating things. The easiest kind of relay to make would be
on activate: self: fire relay
On relay: self: fire relay
On relay: self: event
However, with fire relay east west north south up and down you can make fancy emitter designs and other things as well. Try things out!
On Relay:
On relay is another Input event. Basically, once the brick is "hit" by a relay, this allows the brick to decide what it should do. (So, on relay: self: set color red would make the brick red!)
Set Color:
This event is self explanatory, it sets the color of a brick.
Set Event Enabled:
Set event enabled Allows you to turn on and off events on the brick! Those numbers on the left indicate which event an event is, and the box next to the numbers show whether the event is enabled or disabled through the use of a check mark. To enable/disable an event, use setevent enabled: then put in the number you want to change (of you have more than one then seperate them by commas) and check the box on the far right on or off to choose enabled or disabled.
Obviously these are not ALL the events, but this should be enough to get you started. Once you get the hang of the event GUI it's pretty easy to learn the other events on your own, so long as you know their purpose.
