Posting High-Scores (Hacktendo)

From Hack Wars Wiki

Jump to: navigation, search

This code provides an example of how to use a file on your HD to keep track of the high-scores of players who play your Hacktendo game. It has three parts: a watch script fired using trigger watch, the code in Hacktendo for trigger watch, and an HTTP script that prints out the high-scores.

Posting High Scores: Using Trigger Watch

I have a global parameter in Hacktendo I use to keep track of a player's score. When they beat the game I use trigger watch to report it back to my score keeping watch script. 

triggerWatch("Galaxium","score",getGlobal("score"));


Posting High Scores: The Watch Code

Trigger watch in Hacktendo uses the note on the watch to trigger the watch. In this case, I set the note to "Galaxium". We can note that trigger watch in the previous section corresponds to this. 

string data=readFile("scores");
string records[]=split(data,char(10));
string name=getTargetIP();
string score=getTriggerParameter("score");
float fscore=parseFloat(score);
 
boolean written=false;
string new_data="";
for(int i=0;i<length(records);i++){
	String record_data[]=split(records[i],",");
	String old_name=record_data[0];
	String old_score=record_data[1];
	float old_fscore=parseFloat(old_score);
	if(old_name==name){
		if(fscore>old_fscore){
			old_fscore=fscore;
			written=true;
		}
	}else{
		new_data+=old_name+","+old_fscore+char(10);
	}
}
if(!written&&fscore>30.0){
	written=true;
	new_data+=name+","+fscore+char(10);
}
if(written){
	new_data="";
	boolean inserted=false;
	for(int i=0;i<length(records);i++){
		String record_data[]=split(records[i],",");
		String old_name=record_data[0];
		String old_score=record_data[1];
		float old_fscore=parseFloat(old_score);
		if(fscore>old_fscore&&!inserted){
			new_data+=name+","+fscore+char(10);
			inserted=true;	
		}
 
		if(old_name==name){
			if(old_fscore>fscore){
				new_data+=old_name+","+old_fscore+char(10);
				inserted=true;
			}
		}else
			new_data+=old_name+","+old_fscore+char(10);
	}
 
	if(!inserted){
		new_data+=name+","+fscore+char(10);
	}
 
	writeFile("scores",new_data);
}


Posting High Scores: The HTTP Code

Finally we parse the same file on our website and output the high-scores. 

void outputHighScores(){
	string message="<table width='60%' ><tr><td><b>Player</b></td><td><b>Score</b></td></tr>";
	string data=readFile("scores");
	string records[]=split(data,char(10));
 
	for(int i=0;i<length(records);i++){
		String record_data[]=split(records[i],",");
		String old_name=record_data[0];
		String old_score=record_data[1];
		message+="<tr><td>"+old_name+"</td><td>"+old_score+"</td></tr>";
 
	}
	message+="</table>";
	rc("user1",message);
}
