Scripting movement.

[Angel_Light]

Hello,

Is there any way to just advance the player foreward without reading player x y. Like just if the player is facing north east and the player just presses the up arrow and he moves foreward, north east. Then he rotates and turns south west and pushes the up and the player moves south west.

Is there anyway to do this?

disabledefmovement; will disable the default movement, and then you can script your own movement system from there using keypressed/keydown, and by altering the player's X and Y manually. You will have to do manual onwall detection, swimming, sleeping, and sword use also, though.

For what you're talking about, you'd have to do something like:
player.x += cos(this.angle);
player.y += -sin(this.angle);

this.angle being the angle the player is facing.

ok thank you two

EDIT: Ok i got the image to move but it only moves horzontaly. No matter what direction the player faces. :/
I believe the player.y is being read.

Maybe it's not -sin(this.angle).
Maybe it's just sin(this.angle). Or tan(this.angle). Play around with it, it's been years since I did the X and Y of a sin of an angle (and even then I stood on the shoulders of Sardon)

One problem tho. I'm still Algebra 1. -_- I havent learn sin cos or tan...

Aw, that's so cute.
I see no reason for tan in a movement system.

x,y -> cos(angle), single(angle)
cos is for the x-axis, sin is for the y-axis.
Graal uses angles in radians (0 to pi*2), instead of degrees (0 to 360)
However, if you don't understand radians, you can use the 'degtorad(angle)' function to convert degrees to radian.

player.x += cos(angle) will move the player's x at that angle.
player.y -= sin(angle) will move the player's y at that angle.

The the angle 0 is facing right, then cos(0), -sin(0) will be -1, 0
The angle pi*.25 (.785), or 45 degrees if you prefer that, is between the directions right and up. So, if you use cos(.785), -sin(.785), the player will move to the upper-right.

You could use getangle(gotox - player.x, gotoy - player.y) to find the angle from one point to another.

Oyah, this stuff is trigonometry, not algebra.

Just to clarify, player.y -= sin(angle) is the same as player.y += -sin(angle), Tyhm, you shouldn't post if you don't know what you're talking about. It's not helping anything.

Sweet. A Math Teacher on Graal =B Thanks, i think i'm getting it.....

[Shaun]

Wait wait, who's the math teacher in this post?

[Blitz_Hunter]

probably yen

[Angel_Light]

Yup

[ZeLpH_MyStiK]

tan...if you ever needed to divide the change in y movement by the change in x movement...

I honestly think all he was trying to do was encourage him to play around a little with the script (Judging by him saying he didnt know much about the topic himself) thats all.

Yen you surpise me. Anyway Graal math is screwed up I've never asked graal but i think its a Hybrid version of Trignonometry; Theirs tons of things for starters wtf is up with the X and Y plane?
