-=The extension has now been fixed. Thank-you for testing (and finding a way to fix) the extension, IamCalle=-

Description:
Math Pack #1 provides 24 functions and number series, all in a fast DLL form. This was designed for more advanced GM users who do not want to have to make their own versions of simple math functions.
Download (Geocities)

List of functions:

cross_product_x(x1, y1, z1, x2, y2, z2) - Returns the X axis length of the result vector of the cross product of (x1, y1, z1) and (x2, y2, z2).

cross_product_y(x1, y1, z1, x2, y2, z2) - Returns the Y axis length of the result vector of the cross product of (x1, y1, z1) and (x2, y2, z2).

cross_product_z(x1, y1, z1, x2, y2, z2) - Returns the Z axis length of the result vector of the cross product of (x1, y1, z1) and (x2, y2, z2).

dot_2d(x1, y1, x2, y2) - Returns the result of the dot product of (x1, y1) and (x2, y2).

dot_3d(x1, y1, z1, x2, y2, z2) - Returns the result of the dot product of (x1, y1, z1) and (x2, y2, z2).

quadratic_max(a, b, c) - Returns the maximum of the two results of the quadratic described by ax2 + bx + c = 0.

quadratic_min(a, b, c) - Returns the minimum of the two results of the quadratic described by ax2 + bx + c = 0.

cotan(x) - Returns the cotangent (1 / tangent) of x.

arccot(x) - Returns the inverse cotangent of x.

factorial(n) - Returns n! (all integers under x multiplied).

gcd(n1, n2) - Returns the Greatest Common Divisor (GCD) of n1 and n2. This function rounds the numbers to integers, then works with their absolute value.

lcm(n1, n2) - Returns the Least Common Multiple (LCM) of n1 and n2. This function rounds the numbers to integers, then works with their absolute value.

gold(x) - Returns the Y componet of the Golden Function for X.

bernoulli(n) - Returns the nth Bernoulli number.

fibonacci(n) - Returns the nth Fibonacci number.

perrin(n) - Returns the nth Perrin number.

line_line_collision_check(x1, y1, x2, y2, x3, y3, x4, y4) - Returns whether the line between (x1, y1) and (x2, y2) collides with the line between (x3, y3) and (x4, y4).

line_line_collision_x(x1, y1, x2, y2, x3, y3, x4, y4) - Returns the X value of the collision between lines ((x1, y1), (x2, y2)) and ((x3, y3), (x4, y4)).

line_line_collision_y(x1, y1, x2, y2, x3, y3, x4, y4) - Returns the Y value of the collision between lines ((x1, y1), (x2, y2)) and ((x3, y3), (x4, y4)).

line_circle_collision_check(x1, y1, x2, y2, centerx, centery, radius) - Returns whether the line ((x1, y1), (x2, y2)) collides with the circle at (centerx, centery) with a radius of radius.

line_circle_collision_x1(x1, y1, x2, y2, centerx, centery, radius) - Returns the X value of the first collision between the line ((x1, y1), (x2, y2)) and the circle at (centerx, centery) with a radius of radius.

line_circle_collision_y1(x1, y1, x2, y2, centerx, centery, radius) - Returns the Y value of the first collision between the line ((x1, y1), (x2, y2)) and the circle at (centerx, centery) with a radius of radius.

line_circle_collision_x2(x1, y1, x2, y2, centerx, centery, radius) - Returns the X value of the second collision between the line ((x1, y1), (x2, y2)) and the circle at (centerx, centery) with a radius of radius.

line_circle_collision_y2(x1, y1, x2, y2, centerx, centery, radius) - Returns the Y value of the second collision between the line ((x1, y1), (x2, y2)) and the circle at (centerx, centery) with a radius of radius.

Fast Priority Queues - Game Maker's priority queues are O(n). Mine do everything that Game Maker's do, but in O(log n) time.
Dual-Quaternion Skinning - Modifying vertexes in GM is slow. This simple vertex shader does the job both quickly and well.

Could you post a list of the functions, possibly with some explainations? I'm currently away from my computer, and I'm interested in this. Thanks!

I think that he doesn't want to download it without knowing what it is. I wouldn't either. The description here isn't detailed enough to warrant downloading it.

Done.

I'm open to suggestions.

No, I can't. To do that, I would first have to hack GM, which I do not want to do.

You mean like this?
collision_line(x1,y1,x2,y2,obj,prec,notme)
GM already has a function to determine whether a line collides with an object.

If you wanted to check a collision between a line and the line from an object to a point, (which is what changing x3 and y3 to an object id would probably do) you could just do this:
line_line_collision_check(x1, y1, x2, y2, object.x, object.y, x4, y4)

Very nice :( , but there is a problem..

I installed the extension, and everything works fine... But when i try to play the game, while "saving executeable" it says "cannot find the used extension"

Despite this the functions of the extenxsion work fine...

But will they work on another computer???

I do not know why the problem occurs. I also do not have registered GM7, so I can't test the extension...

I'd try uninstalling and reinstalling the extenstion.

I uploaded a version that should fix the problem.

New features:

Removed an extra line from the "Uses" part (should fix error)
Changed help lines to be more useful.
Fixed some argument counts.

EDIT: IamCalle tested it for me, and when a bug was found, figured out how to fix it. Thanks.

Here you go:
Download mirror #1
Download mirror #2

I re-checked and re-built the extension minutes ago, really there should not be any errors (works here, yet again).
