Adding Enemies in different waves
To add 50 enemies, you can use a for loop:
To add two enemies every two seconds, you can do this:
I am not too sure what you meant with the last part, the wave trigger. Two new enemies are spawned every two seconds, should a new wave start whenever one of those enemy pairs are killed or whenever there is no enemy object in the world?
public void newWave()
{
for (int i=0; i<50; i++)
{
addObject(new Enemy(), /*x-position*/, /*y-position*/);
}
}private int enemySpawnTimer = -1;
public void act()
{
if (++enemySpawnTimer == 55*2)
{
enemySpawnTimer = 0;
for (int i=0; i<2; i++) addObject(new Enemy(), /*x-position*/, /*y-position*/);
}
}What i mean is that when fifty enemies are spawned. then the spawning stops and once all of them are killed a new wave starts
So you mean the wave is 25*2 enemies?
private int enemySpawnTimer = 0;
private int spawnEnemies = 0;
public void act()
{
if (spawnEnemies > 0)
{
if (++enemySpawnTimer == 55*2)
{
enemySpawnTimer = 0;
spawnEnemies -= 2;
for (int i=0; i<2; i++) addObject(new Enemy(), /*x-position*/, /*y-position*/);
}
}
else //no enemies will spawn in this wave anymore
{
if (getObject(Enemy.class).isEmpty()) //no enemies in the world
{
spawnEnemies = 2*25;
}
}
}
Lines 15 through 21 should handle that.
You have to change 'getObject' to 'getObjects' in line 17.
I'm getting an error with line 12 and even when putting in getObjects and error still occurs
What is the error message?
Did you put in values for x and y?
i have put in the x and y coordinates and the error says that it cannot find symbol - method addobject(Enemy,int,int) and the it is the same for the get objects method (java.lang.Class<Enemy>)

Can you show me what that code would look like?You need to login to post a reply.
