So I have walked myself through the tutorials(was amazed sounds and music were so easy) and have been studying the sample game provided with SGDK2 like crazy, but there are a few things I can't get...and some stuff I just wanted to learn.So Here goes.
1. I can make solid tiles and all the other tiles. but how do I make solid sprites? It just wont work for me when I tell the sprite it is a solid when I am editing the map. I have looked at the sample and I must be missing something.
Sprites don't have solidity. They can react to tiles (ReactToSolidity) and they can collide with other sprites (triggering some action defined by rule functions), but sprites can't react to other sprites as if they were solid. In order to simulate this, you need to treat a sprite as a platform, which allows another sprite to walk on it, or come up with your own rules for how to behave when two sprites collide. There aren't built-in functions (yet) to make sprites avoid each other except for the platform riding behavior (if that counts).
If you're confused by the "Solidity" property of the sprite, you should know that that determines which solidity definition the sprite uses to react to tiles (determines which tiles the sprite sees as solid).
2. I want to be able to make a counter go down when a sprite collides with another sprite. In example, I have an enemy bullet and when it collides with the players sprite I want my Health counter to go down by 1. I have looked at the testcollisionmask, or something like that, but I am not sure how to get it to do what I want.
Add a sprite category named "Bullets" and put your bullet sprite definition(s) in it. Then in the player sprite definition, add a parameter named "TempNum" if you don't already have one, and then add a rule:
Do, TestCollisionMask
Targets: ParentLayer.m_SpriteCategories.Bullets
Output to: TempNum
Then another rule:
If, >=
left operand: TempNum
right operand: 0
And inside the If:
Do, ChangeCounter
Counter: Counter.Health
Operation: CounterOperation.DecrementAndStop
End If
3. I think I can figure this one out on my own after I can get question 2, but I might as well throw it in there. When my health hits 0 I want to just reload the map for now. but eventually I want to be able to freeze frame on that screen for a few seconds and then reload the map.
Freezing all the sprites might be difficult, but if you just want to freeze the player sprite, you could add a "dead" state to your player sprite, and make sure that you only process the rules when the sprite is not dead:
If, Not, IsInState
FirstState: (int)Sprites.Player.State.Dead
LastState: (int)Sprites.Player.State.Dead
(Include all your rules here, and then...)
1. Else, ChangeCounter
Counter: Counter.DeathCounter
Operation: CounterOperation.IncrementAndLoop
2. If, ==
left operand: Counter.DeathCounter.CurrentValue
right operand: 0
3. Do, LoadGame
Slot: 0
InMemory: true
(assuming slot 0 is where you saved the reset current map in memory)
4. End If
