Video debate: Can't a game that can't jump be a 3D game?

Although the above question and answer is just a joke circulating in the industry, it also shows how important the function of "jumping" is in the current online games. Some players can't jump down because of a certain game, and choose to leave the game immediately after trying. Some players even think that online games that can't jump are not 3D games. Most of the 3D games that come out recently have the function of jumping, but there are many kinds of jumping. Some games can't move forward when they encounter a little bump, so they can only make a detour. In some games, jumping can be compared to lightness skill. No matter how high the mountain is, you can jump. Some games can only jump vertically in situ, and some games can jump twice or infinitely in the air. In most 3D games, "jumping" is very important, which has a great influence on evasion and attack. It can be said that the function of "jumping" is one of the important feel foundations for players in the game. World of Warcraft, which has always been very popular, has made the function of "jumping" a necessity in the game, and pressing a few spaces when something is ok has also become a habitual action of fans of World of Warcraft. Let's review the martial arts online game "House of Flying Daggers" adapted from the movie of the same name. Although Zhang Yimou was invited to carefully plan the game, it's a pity that the game can't jump so far. It's really strange that the game doesn't support the function of jumping under the background of martial arts flying for the world. Speaking of martial arts flying, I have to mention meteor butterfly sword. Players who have played meteor butterfly sword must be very worried about the "jumping" memory of this game. This game is based on Gu Long's martial arts novel of the same name. In the game, you can not only jump in the air, but also fly over the eaves. There are even special flight videos on the Internet. Steam Fantasy is an mmorpg game based on steampunk. In the game, players can ride hot air balloons, flying boat, steam knights and so on. But the game doesn't support "jumping" either. Recently, the technical test of "Journey of Wind and Fire" is completely opposite to "Steam Fantasy", which not only can jump at will, but also adds the function of riding and jumping.
