Interactive NPCs
Well, I was asked to explain how one NPC could interact with another in the same level! Here's what I came up with.
Here's what calls the object.
PHP Code:
function onCreated()
{
this.setShape(1, 32, 32);
this.setImg("block.png");
}
//So, the player touches the object
function onPlayerTouchsMe()
{
//If the NPC has already been touched
if (this.hasCalled)
{
//Then ignore the rest of this code and just return nothing
return false;
//Else carry on with the script
}
//Now, we say that the NPC has already been touched!
this.hasCalled = true;
//Now, look below and we have the line 'level.objectPosition'
//Well, this is a global variable inside of the level! We can call this
//variable from any NPC in the level.
triggeraction(level.objectPosition[0], level.objectPosition[1], "Called", "");
}
Here's the object that shall start interactive once the above object has been touched.
PHP Code:
function onCreated()
{
this.showCharacter();
//This is needed for the action to be called
this.setshape(1, 32, 32);
//This is a GLOBAL LEVEL VARIABLE
level.objectPosition = {this.x, this.y};
}
function onActionCalled()
{
//Make some fancy messages to display
temp.messageInformation = {
"I see, that you've found my hidden object!",
"Just for that, you shall perish!",
"It's been a pleasure talking with you though!",
" "
};
//Now display these messages to the player
this.chat = temp.messageInformation[this.messageDisplay];
//If the chat is displayed as nothing, make sure that it
//doesn't carry on doing the rest of the script
if (this.chat == " ")
{
return false;
}
//Now, basically it displays the messageInformation
//at a specific index, 'this.messageDisplay' will control
//which index to display
this.messageDisplay++;
//Repeat this process every five seconds!
this.scheduleevent(5, "ActionCalled", "");
}
I hope this explains a few things! |
