hey, i'm making a 2d-platformer using gamemaker lite. i really am having trouble getting it so when I click "spacebar", arrows come out of my sprExplorer sprites bow, depending on which way im facing. eg. facing left, press space, fire left, facing right , press space, fire right.
I also want to make it so I can only fire 1 arrow per 2 seconds (to prevent Overpoweredness)

please, be VERY detailed.
DragNdrop or GML code is fine,
but if you do GML please be very specific on the coding, im new.

thanks

Well, you have to make a 2-second alarm after you shoot an arrow. In more detail:

First, initialize a variable and you can call the variable global.arrow_shoot. Basically, put this code in the Explorer's Create Event:

{global.arrow_shoot=1}

Now, you specify that is you press Space, and if global.arrow_shoot=1, create an instance of the arrow object, and then turn global.arrow_shoot to 0. Put this in the Step Event of the Explorer:

if (global.arrow_shoot==1)  {instance_create(x,y,obj_arrow); global.arrow_shoot=0; alarm[0]=60}

Then, you have to specify the speed and direction of the arrow object whenever one of its instances is created. Put this in the Create Event of the arrow object:

{speed = /*insert speed here*/; if (obj_explorer.direction==180) {sprite_index = /*insert name of arrow sprite facing left*/; direction=180;} else if (obj_explorer.direction==0) {sprite_index= /*insert name of arrow sprite facing right*/; direction=0;};}

You can see above that I put alarm[0]=60. This means that whatever we have set in the Alarm 0 event is going to occur in 60, and there are 30 steps in 1 second, so basically 2 seconds. Now, since we haven't done so already, we must set the Alarm 0 event of the Explorer, which will have the same code as we put in the Explorer's Create Event:

{global.arrow_shoot=1

That means that 2 seconds after you press Space, global.arrow_shoot will equal 1, thus, you will have the ability to shoot arrow again.
