    <p>i am making a game similar to fruit ninja. birds flying down the water and then up (just like fruits up side down)</p> <p>but some of the birds fly too far and the others too near. can someone check my code? vy should quite close to each other.(vx is not a problem)</p> <pre><code>static float tuna = 10.0f; -(void) reset { float vy = 0.0f; float vx = 0.0f; int sign = 1; if (CCRANDOM_0_1() &gt;= 0.5) { sign = -1; } float hurry = 0.0f; if (CCRANDOM_0_1() &lt;= 0.1) { hurry = 1.0f; } switch (birdType) { case BirdType1: vx = 1.0f * sign + (CCRANDOM_0_1() - 0.5f) * 0.08f; vy = -6.5f; break; case BirdType2: vx = 1.5f * sign + (CCRANDOM_0_1() - 0.5f) * 0.08f; vy = -6.2f + (CCRANDOM_0_1() - 0.5f) * 0.1f; break; case BirdType3: vx = 1.0f * sign + (CCRANDOM_0_1() - 0.5f) * 0.1f; vy = -5.8f - hurry; break; default: [NSException exceptionWithName:@"BirdMoveComponent exception" reason:@"unhandled bird type" userInfo:nil]; break; } velocity = CGPointMake(vx * 5, vy * 5); if ((int)([[GameManager sharedManager] score] / 100) &gt;= prevLevel) { if (tuna &lt;= 12.0f) { tuna += 0.01f; } prevLevel = (int)[[GameManager sharedManager] score] / 100; } } -(void) update:(ccTime) delta { if (self.parent.visible) { NSAssert([self.parent isKindOfClass:[BirdEntity class]], @"node is not an entity"); BirdEntity* bird = (BirdEntity*) self.parent; bird.position = ccpAdd(bird.position, ccpMult(velocity, delta * tuna)); velocity = ccpAdd(velocity, ccpMult(acceleration, delta * tuna)); acceleration = ccp(0, 0.3f); float birdHeight = CGRectGetHeight([bird boundingBox]); //20 is the bottom trap if (bird.position.y &lt;= (birdHeight / 2) + 20) { [bird dieAccidently]; } if (CGRectIntersectsRect([GameScene screenRect], [bird boundingBox]) == NO) { bird.visible = NO; [bird stopAllActions]; [bird unscheduleAllSelectors]; [bird unscheduleUpdate]; [self reset]; } } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
