Which quickly becomes the shortest way to go about this as the case count grows. Type = obj_a type = obj_b type = obj_c types = 3 for ( var t = 0 t < types t ++ ) Here's to another reasonable thing - pushing the things in question into an array: With ( obj_a ) scr_check_outside ( ) with ( obj_b ) scr_check_outside ( ) with ( obj_c ) scr_check_outside ( )Īlso, contrary to the popular belief, scripts aren't that slow - in fact, a script call alone takes about the same time as a variable assignment does, so the overhead is neglectable for most cases.

You could then simply call it from each with-loop: / scr_check_outside() if ( y < 0 ) instance_destroy ( ) When presented with a snippet of code that is used in multiple places it's a pretty reasonable thing to move it into a script. It is not ideal and duplicate code means more trouble with editing, but this is most often used. With ( obj_a ) if ( y < 0 ) instance_destroy ( ) with ( obj_b ) if ( y < 0 ) instance_destroy ( ) with ( obj_c ) if ( y < 0 ) instance_destroy ( ) The simplest solution is to include multiple blocks of code (one for each value): So let's consider your options for applying a piece of code to all instances of several types: Sometimes you can cheat by applying the expression to a shared 'parent' type of objects, but that is not always the case (and can have side effects if there are more object types meeting the condition). However, initially the same block can not be applied to multiple values, and that's less handy. This can be rather handy under the multiple circumstances. With ( obj_bullet ) instance_destroy ( ) Or an object type (and will apply the expression to each instance of it):

Var bullet = instance_create ( x, y, obj_bullet ) with ( bullet ) direction = 180 As you may know, GameMaker Language has a Pascal-like 'with' structure:īut it's not exactly like the Pascal version.
