Initialise two variables like so: drawlength=0 They appear longer, and they appear to point away from the centre. You’ll notice that, as the poles get further away from the centre, from a 2D perspective two things happen. Imagine you’re looking down on an area, where a number of poles are stuck into the ground perfectly vertically. x2 and y2 will be where the perspective is given. Open up Draw, put in something like “ draw_set_color(vk_red)” just to make sure it’s visible when drawn, then follow it up with the start of a draw_line code. It doesn’t need a sprite, it will be drawn to be visible. Now, to start with some fake 3D, make another object, calling it oPole.

Make a new room, put the background in with it looping forever, put the guy somewhere in the room, and activate views and View 0 (tick “Enable the use of views”, make sure View 0 is highlighted, then click “Visible when room starts”) but DO NOT have it set to follow the player character (this is already done with the two last lines of code above, and holds the extra advantage of not stopping when the view hits the end of the room). Make a quick background which just needs to be a non-solid colour. Create a circular sprite (centralising its origin), give it an object and name it oCircle, and put this in Step: if keyboard_check( vk_left) view_xview= x-320 Furthermore, he should be taking the screen view with him as he moves. Okay, so for the first little fake 3D test, you’re going to need a circle, which you can move with the directional buttons. If you still don’t understand lengthdir, look up some other tutorials on Game Maker Community – there are many very helpful ones. Of course, it’s unlikely you’d need anything to be relative to (0,0), so your typical code may be something like: oBall.
Their purpose is to give you a coordinate, if you take (0,0) and translate it len pixels in the direction dir (note the way direction is done in GM – 0 degrees is right, 90 degrees is up, 180 degrees is right, 270 degrees is down). The GML code for the functions are (and note that you’ll pretty much ALWAYS use them as a pair): lengthdir_x(len,dir) If you don’t, it doesn’t take much to learn – here’s something that will hopefully help.
#GAME MAKER STUDIO 2 3D HOW TO#
So how do you?įirstly, you should know how to use lengthdir_x and lengthdir_y properly. There are plenty of things you can do with it. You can ignore the concept of perspective. You can draw something ontop of another without any of those odd graphical issues where the two seem to keep “striping” into each other. It’s much easier to manipulate object depth manually. This may just be seen as a ploy for attention – “why use fake 3D when Game Maker has REAL 3D built-in right off the bat?” Well, there are advantages to it.
A technique I frequently use in games is fake 3D.
