Put the following code into these events: In obj_jumprefine, edit these values: Depth -1 Keep in mind that this system is very basicĪfter that, make 12 objects and name them: obj_jumprefine, obj_wall, obj_movingwall, obj_movingwall2, obj_onewayplatform, obj_enemy, obj_enemy2, obj_enem圓, obj_emblem, obj_coin, obj_goal, obj_checkpoint You should use scr_death if you want certain aspects of progress to remain in memory But because it restarts the room, global variables for things such as collectables and coins will not be kept intact Because the Creation Code sets the checkpoint system, room_restart or scr_death will achieve the same thing, make the player spawn on an active checkpoint In my example, the enemies have room_restart that makes the player start the room over whenever they touch the enemies and have not jumped on top of them Then the fourth line will spawn the player at the beginning of the level, but only when the conditions of the first two lines has not been met The third line checks if the conditions of the first two lines has not been met The second line enclosed in a curly bracket will spawn the player in the checkpoints position In the first line, it checks if a checkpoint is activated (if checkpoints are not off) The player will never see this room, but is needed in order to make checkpoints work properly Global Variables are values that carry their functions across all aspects of a game Make a room called rm_initialise and only put in Creation Code and room_goto_next This system needs Creation Code in order to operate In the script, put in the following code: You can make the sprites anything you want, but its best to work with basic coloured squares) Make 10 sprites and name them: spr_wall, spr_player, spr_moving_wall, spr_movingwall2, spr_onewayplatform, spr_enemy, spr_emblem, spr_coin, spr_goal, spr_checkpointĭouble click on the sprites and give them the following properties:(The properties can be edited with these GUI interfaces.

While not overwhelming, 2D platformers are a reasonable step up from basic maze and space shooter projects.Īfter a month of development, I will show you how to make a 2D platformer foundation straight forward enough to develop, but simple enough so you can add your own ideas for a 2D platformer game. It needs calculations of horizontal movement, Creation Code for a basic checkpoint system and novice developers often stumble because they underestimate what goes into a 2D platformer. Making 2D platformers in GameMaker Studio involves more than jumping a character up and down.
