how to use p3dc_set_modrot()? Cant seem to create rotated primitive masks

[The Scorpion]

p3dc_add_triangle() does not work !

it just ends the game without any error report O.o

I changed it, exporting the model, then loading it with

p3dc_add_model()

the same thing happens again

however all the other functions work well :D (p3dc_add_block(), collition detection, etc ...)

No idea how to solve it .... any help appreciated !

Note : I used to use p3dc in my older projects ! but this time it crashes !!!!

Well in my game my crosshair moves not my player. Moving code. Please help thanks

friction = 0.5

if mouse_check_button_pressed(mb_left) then
{
var obj;
obj = instance_create(x,y,obj_bullet)
obj.z = z
obj.speed = 10
obj.zdir = (zto-z)/(100/obj.speed)
obj.direction = direction
}

var dis;

if mouse_check_button(mb_right) then zoom = 40 else zoom = 0

if(keyboard_check(vk_left) or keyboard_check(ord('A'))){
x+=lengthdir_x(0.4*(keyboard_check(vk_shift)+1),direction+90);
y+=lengthdir_y(0.4*(keyboard_check(vk_shift)+1),direction+90);
}
if(keyboard_check(vk_right) or keyboard_check(ord('D'))){
x+=lengthdir_x(0.4*(keyboard_check(vk_shift)+1),direction-90);
y+=lengthdir_y(0.4*(keyboard_check(vk_shift)+1),direction-90);
}
if(keyboard_check(vk_up) or keyboard_check(ord('W'))){
x+=lengthdir_x(0.4*(keyboard_check(vk_shift)+1),direction);
y+=lengthdir_y(0.4*(keyboard_check(vk_shift)+1),direction);
}
if(keyboard_check(vk_down) or keyboard_check(ord('S'))){
x+=lengthdir_x(0.4*(keyboard_check(vk_shift)+1),direction-180);
y+=lengthdir_y(0.4*(keyboard_check(vk_shift)+1),direction-180);
}

Is only using raycasts a viable way to check collisions for a 3D platformer? Would you do a few raycasts spread across a circle to check the bottom (and sliding along a plane found with the averaged distances) and then raycasts forward from the "front" of the circle about halfway up to check for walls (again, sliding along a plane found from the averaged distances)? Here's an image to describe what I mean if my explanation isn't good:

Hi all,

First of all i want to make a verry basic fps using this.
but if i load a map(.3d3) the game starts but then windows says : (FILENAME).exe doesnt work anymore.
And then te game stops, the examples with the external map work, but if i wanna change them i get that error?!
Im using Game Maker 8, on a 64bit win 7 pc.

I'm having big trouble with P3DC :

-First, (as other people said before, I think) I can't load my d3d maps ! They're made in Sketchup, exported to .obj or and then converted to d3d using GmModelFix, but I only have an unexpected error !

-Second, I NEED to change a little the built-in collision checking code (in the examples). I want to implent rotation support (player collision model can rotate). What I obtain : player is stucking in walls.
I know I must add something in the 2nd and 3rd blocks
of code (inside the 1st block).
But I can't really imagine what.
Code :

//End Step Event. Original code from P3DC's examples. Changed a bit for specific use in own game.

arg0=playerCollisionId
arg1=0.25 (arbitrary value)
arg2=6-crouch (Z height of model)
arg3=global.levelCollisionId

var tox,toy;
tox=x
toy=y
x=xprevious
y=yprevious
tdir=point_direction(x,y,tox,toy);
tdist=point_distance(x,y,tox,toy);

if(p3dc_check_rotation(argument0,tox,toy,z-argument2*0.6,argument3,0,0,0,0,0,dir_look)==1){
        if(p3dc_check_rotation(argument0,x+lengthdir_x(argument1,tdir),y,z-argument2*0.6,argument3,0,0,0,0,0,dir_look)==0){
        x+=lengthdir_x(argument1,tdir/*+radtodeg(arctan(p3dc_triangle_data(11)))*/)
        }
        if(p3dc_check_rotation(argument0,x,y+lengthdir_y(argument1,tdir),z-argument2*0.6,argument3,0,0,0,0,0,dir_look)==0){
        y+=lengthdir_y(argument1,tdir/*+radtodeg(arctan(p3dc_triangle_data(11)))*/)
        }
        }else{
    x=tox
    y=toy
    }

Thanks to all, and please help !

Im also still having this problem, but it seems like nobody responds on this forum :s

Thanks to all, and please help !

Main part of the problem solved (posting if other had the same problem ): the variable representing the x,y,z, rotations must be in RADIANS ! Use degtorad(x) !

i get an unexpected error message when trying to load a d3d model? any help?
i use sketchup and gmmodelfix to do my models

[brett14]

For those encountering errors, I have updated the first post with instructions that seem to work for me. Please report back if they work or not.

Yeah, that 5112 GMMC 5.0 1.0000 1 1.0000 0.0000 1 1 0 0 0 probably break my gmmodelex code as well as I am using fscanf with %g to read the data, and there is no need to do a read line with that function... In my case it probably blow up trying to read GMMC as a double... or reading the extra values on the line as model points.


I myself added data at the end of the file (texture used and some other bits) I assumed people would use the numlines at the top to guide their loop. Probably not a good idea either.

[brett14]

You're welcome

Yes thank you. I did see your example and used it (want credit?). I've never encountered problems myself because I make all my models in such a fashion that these problems don't arise. I have not used gamemaker in several months now, as I am bogged down with school and prefer to work on my engines in C++ (which also contributes to the problem of me not finding bugs).


@Icuurd12b42
I'm doing the same thing (or very similar). It may have been you (pretty sure it was) who helped me read model data a couple years back. Source for my model loading code is posted. I'm using fscanf(...) with %f

No, no, it's fine

I just hope it gets fixed soon, so I don't have to keep changing the second line. I often forget to.

Talk to the guy who decided to add non gm model data in the middle of the gm model data of the gm model file. Is it GM Model Creator or something?

I don't think Maarten works on that model creator anyomre, I think he only does C++ now.

[NikaB]

Yes, but I think he actually continues to respond to the Extreme Physics topic... Isn't it ?

[brett14]

Same thing here. I have not used gamemaker in over 6 months, yet I still respond to [some] posts on this. I've been using C++, and have not even used my own dll since V5.00. I have been working on a project for just under a year that many of you will find interesting.
Anyways, please don't get off topic (I realize I just did too). If you wish to contact Maarten do it via PM or some other method. Please don't discuss his forum activity here.

Thanks!
