I'm working on a simple roguelike mechanic, how to use Manhattan Distance to calculate the best movement spot. I know the code is close. It runs in alarm[0] of the enemy, as it's turn based and I call this alarm whenever the player moves. I have a simple script that calculate Manhattan distance and I know that functions correctly. However, the AI doesn't always move toward the player, sometimes it's failing to move closer to the player and close the gap. You can stalemate the AI going left and right or up and down.
I notice if the player moves left or right, the AI won't move up or down to close the difference and vice-versa. Also linked the .yyz for ease.
Manhattan distance script:
function manhattan(spot)
{
return(abs(spot.x-oPlayer.x)+abs(spot.y-oPlayer.y));
}
Enemy alarm[0]
//get grids around us
if instance_place(x-64,y,oGrid)
{
left=instance_nearest(x-64,y,oGrid);
}
if instance_place(x+64,y,oGrid)
{
right=instance_nearest(x+64,y,oGrid);
}
if instance_place(x,y+64,oGrid)
{
down=instance_nearest(x,y+64,oGrid);
}
if instance_place(x,y-64,oGrid)
{
up=instance_nearest(x,y-64,oGrid);
}
//move or attack
nu=current_grid;//don't move if not better
if manhattan(up)<manhattan(down) && up.open==true
{
nu=up;
}
else if manhattan(down)<manhattan(up) && down.open==true
{
nu=down;
}
else if manhattan(left)<manhattan(right) && left.open==true
{
nu=left;
}
else if manhattan(right)<manhattan(left) && right.open==true
{
nu=right;
}
else if manhattan(up)==manhattan(down)//need to go left or right
{
if manhattan(left)<manhattan(right) && left.open==true
{
nu=left;
}
else if manhattan(right)<=manhattan(left) && right.open==true
{
nu=right;
}
}
else if manhattan(left)==manhattan(right)//need to go up or down
{
if manhattan(up)<manhattan(down) && up.open==true
{
nu=up;
}
else if manhattan(down)<=manhattan(up) && down.open==true
{
nu=down;
}
}
x=nu.x;
y=nu.y;
nu.open=false;
current_grid.open=true;
current_grid=nu;
Going back to thailand again next month. For my first trip, I used almost exclusively MRT for travel, in chiang mai I took some buses around.
I have not had a good experience with the thai tuktuk/taxi drivers who always try to scam me as a foreigner.
Since I heard grab is widely used in asia, and I assume it's used often in thailand as well.
When you guys travel from let's say, Asok to Khao San Road, which is not too far by car, but a considerable distance to walk, do you guys usually take the MRT followed by tuktuk or taxi? Because I want to use Grab as the alternative in cases like this
Also, what if you guys are on islands like Koh Tao/Phangan/Krabi Phuket, is grab used here at all as well?
Hi - I'm writing up my grandfather's WWII stories, and in May of 1940, he was living in Brussels, Belgium. My grandmother had their first child a few days before the Nazi invasion. She gave birth in a maternité about 2 miles from their apartment, and I've verified that the streetcars didn't run past midnight, so it seems likely they summoned a taxicab. How did one summon a taxicab in the middle of the night? Was there some sort of central dispatch he could call? Did he got to a main road and flag one down? Something else?
