By setting the x (and y) values you can make the object jump around the room to the position of your choice, or you can add and subtract to them by smaller amounts to give the illusion of movement without actually using the built in speed and direction functions. This should be taken into account when making your games as often one type of ...

2013年1月15日 · xpos = instance.x; ypos = instance.y; where instance is the instance id (gained through some method, object id can be used if the instance is the only instantiation of the object). To start moving towards a position you should set the speed & direction: direction = point_direction(x,y, instance.x, instance.y); speed = WANTEDSPEED;

这个函数返回由指定分量[x1,y1]和[x2,y2]组成的矢量的方向，与固定的x/y坐标 room 。例如，在下面的图片中，如果我们想得到从玩家飞船位置到敌人位置的方向，以便我们可以向敌人发射导弹，那么我们将使用这个函数（具体代码见图片下面的例子）。

2017年12月13日 · I'm currently trying to use draw_healthbar on an object that is 32x32. After doing some research, my understanding is the very top left pixel in my object is x = 1 and y = 1. When I use the command to draw the healthbar and I draw it at (x+6, y-19, x+25, y-21) it places it completely outside of the object high and right.

2016年8月8日 · It's possible to get the actual possition (X and Y) of an object in the view? Example: I have a view of 100 x 100 and a room of 200x200. I place and object in the room in the x = 150 and y = 150 When the room start the object is outside the view.

2021年7月19日 · gml: camX = camera_get_view_x(...); camY = camera_get_view_y(...); xx_relative = camX + 150; yy_relative = camY + 150; If your purpose is to draw things on the screen, use the Draw GUI event.

lerp the position (x,y) coordinates of an instance, to smoothly approach a position: x = lerp(x, destination_x, percent); y = lerp(y, destination_y, percent); lerp the speed to smoothly accelerate or decelerate to a target speed. speed = lerp(speed, desired_speed, accl); lerp direction, to smoothly turn towards a desired direction.

在 GM 中，左上角为原点，向右为 x 轴正方向，向下为 y 轴正方向。 其中角度以正右方为 0，正上为 90，正左为 180，正下为 270。 角度超出 0~360 的范围是允许的，比如 -90 和 270 在 GM 中都是指正下方。

2016年8月22日 · If you want to check that its position is exactly on a point then you'll have to iterate through each instance of the object and check if it's x and y position match the point. if(x == check_x && y == check_y) { return id; You could probably use instance_place or instance_position with the all keyword. you might need to be more specific.

x = (x & $ffffffe0) + 32; if (y ^ $1f) > 0 {do something...}; You can find additional information on how to use the bitwise operators and what they do from the section: Bitwise Operators.
