Hey,

I'm having some problem using c_scan with my pathfinding project. I need to scan in a node (it's A* based), and I'm creating bitmaps to see where the nodes are. But unfortunatly these get scanned as entity's too, so it can't find a free path (without entity's). How do I solve this, because it doesn't detect the other entity's too

Here's the code:
Code:

---

void CalcUsableNodes()
{
	var i;
	var j;
	for(i=0; i<gridWidth; i++) //loop through width nodes
	{
		for(j=0; j<gridHeight; j++) //loop through height nodes
		{
			tmpModel = ent_create("under.bmp",vector((j*64)+32,(i*64)+32,5),NULL);//create a bitmap to see where the node is
			Snap(tmpModel); //make sure it's in the right position
			var scanResult = c_scan(vector((j*64)+32,(i*64)+32,1),tmpModel.pan,vector(360,0,32),SCAN_ENTS|IGNORE_ME); //scan for ents
			if(scanResult == 0) //if no entity is found
			{
				nodes[(i*gridWidth)+j] = 1; //this node is clear for walking
			}
		}
	}
}

Unfortunately all of the nodes stay on 0 (their initial value). Maybe there is a problem with the c_scan?

Thanx,

anyone??

SCAN_LIMIT : Finds only entities with ENABLE_SCAN set, or only static lights whose range can reach the scan origin. Can be combined with SCAN_ENTS and SCAN_LIGHTS.

Why dont you use SCAN_LIMIT. Check the help file for c_scan and and you will find it there.

with scan limit it doesn't work either, the nodes on which the models stand are still regarded as open for walking this is the action I use for the models:
Code:

---

action ScanModel()
{
	my.emask |= ENABLE_SCAN;
}

---

can you use a id

action node
my.id =6000;

function
if(event_type == EVENT__SCAN)
if(you.id == 6000)


would that work? I'm new to this and my pointfinding system uses is to tell entities apart.

The problem is that the objects which are placed onto some nodes don't get scanned. They need to get scanned so I can tell which nodes are free and which aren't
