My game is very similar to the hidden game in chromes web browser. I have a character that needs to jump over incoming enemies. Is there any way i can know when to send an incoming enemy? Some of the factors to take in to account i guess are the speed of enemies, height of jump, speed of jump, and dimensions of bitmaps (that represent character, and enemies).

Thanks

Something as simple as this would give you the rough time the player will have to react if you were to spawn an enemy right now.

minReactionTime = 0.5; //Give the player half a second to react
closingSpeed = enemySpeed + playerSpeed;

if ( (enemySpawn - playerPosition) / closingSpeed >= minReactionTime )
{
   spawnEnemy();
}

  • \$\begingroup\$ Basically it just calculates how long it will take the player and enemy to collide if they continue moving forward at max speed. This gives you a rough estimate of how long the player will have to react if you spawn an enemy at the "enemySpawn" point in that code. \$\endgroup\$
