#Gamemaker studio 2 for loop code

The with statement has the following syntax:įor the expression, you can indicate one or more instances (or a struct) to perform the code on, using an instance ID, the object ID (which indicates that all instances in the room of this object are to run the code block), the struct ID, or one of the special keywords ( all or other). So how do we achieve something like this? This is why the with statement exists in GML. It will have exactly the same effect because it is simply an abbreviation of the first statement. Next this new value is set as the y-coordinate of all balls, so the result is that all balls get the same y-coordinate, and even if you use the following: You may think that this is achieved simply by the following piece of code:īut this is not correct, as the right side of the assignment gets the value of the y-coordinate of the first ball and adds 8 to it. For example, imagine that you want to move all the instances of a ball object in your game 8 pixels down. However, in a number of cases you want to do a lot more than just change a single variable within those other instances, and may want to perform more complex code actions that require multiple functions and lines of code. As indicated in the section Addressing Variables in Other Instances, it is possible to read and change the value of variables in instances and structs other than the one currently executing any given code.
