示例1: sin
void AI::enemy2Update(Enemy &enemy, const float dt)
{
//this will represent the max distance the enemy can moe up and down
float maxAmplitude;
//create a vector to change for the new enemy position
D3DXVECTOR3 tempVel = enemy.getPosition();
//increment the y-position to follow a sine curve
tempVel.y = maxAmplitude * sin(dt * 0.5f * PI);
//increment the Xposition by the EnemySpeed
tempVel.x = tempVel.x += ENEMY_SPEED;
//normalize the vector
D3DXVec3Normalize(&tempVel, &tempVel);
tempVel *= ENEMY_SPEED;
enemy.setVelocity(tempVel);
// Check if enemy should fire a missile
float missFireRate = enemy.getMissileFireRate();
enemy.setMissileFireRate(missFireRate -= dt);
if (missFireRate <= 0.0f)
{
enemy.fireMissile(D3DXVECTOR3(0.0f, -5.0f, 0.0f)); // TODO: Modify for a fixed missile speed constant
enemy.setMissileFireRate(ENEMY_MISSILE_FR);
}
}示例2: enemyBossUpdate
//////// Boss moves down into game screen ////////
//////// then begins its attack run ////////
void AI::enemyBossUpdate(Enemy &enemy, const float dt)
{
// Move into game screen
if (enemy.getPosition() < D3DXVECTOR3(0.0f, 20.0f, 0.0f)) // TODO: Modify for constant Y position value
{
D3DXVECTOR3 vel = D3DXVECTOR3(0.0f, -5.0f, 0.0f);
enemy.setVelocity(vel);
// Uncomment if needed
//enemy.setPosition(enemy.getPosition() += vel * dt);
}
else
{
// Begin attack run
// Fire bullets

// Cannot specify where to drop mine
// Mines are listed as a pickup, are they intended to be picked up by the player?
