Change one part of the jump at a time
Two decisions affect a cactus jump: when you start and how long you hold the jump key. Starting sooner is not the same as jumping higher. A long early jump can put the dinosaur back on the ground before the obstacle arrives.
Use Space or the up arrow after focusing the player. The local edition responds to releasing the jump key, so practice short presses and longer holds separately. There is a minimum jump motion; a brief tap does not make the dinosaur instantly return to the ground.
Use the collision to choose an adjustment
- You reach the cactus before gaining height: try taking off earlier.
- You come down onto the obstacle: check whether the jump began too early or ended too soon.
- You clear one group but cannot prepare for the next: examine the landing space as well as the first group.
These are diagnostic possibilities, not a frame-perfect timing formula. Watch the whole jump before choosing which variable to change.
A fixed screen distance is not a permanent cue
The runner speeds up during a run. An obstacle at the same visible distance can leave less time to react later. Screen width and the local edition’s mobile speed adjustment also make universal pixel measurements unreliable.
At a comfortable early speed, learn the relationship between the leading cactus edge and your takeoff. Later, adapt to the obstacle’s approach rather than counting on the exact same visual gap.
A short cactus drill
On one run, keep your jump duration fairly consistent and adjust takeoff. On another, compare a tap with a longer hold when there is space to land. Judge whether you cleared and recovered, not just whether the score increased.
Our recorded score-615 frame shows an airborne dinosaur, but a still image cannot establish an ideal key duration. These timing exercises are based on the local controls and mechanics; bird-height and high-score tactics were not validated in that session. Next, read about landing mistakes.
