Can anyone help me with collision response o:?

Damir

Ugh, @CodeAssasssin, by now you should now to just ask your question and pray to the ancient gods that someone who has an idea is here ;P

Lol

Question is: How exactly do I prevent my object/entity from entering a another entities bounds

But handling collision response before it actually moves?

I really haven't worked that much with collision so :(

In my engine, I check if the next position would mean a collision, and then I change the velocity to just exactly touch the other object.

1:59 AM

o: That sounds pretty simple lol - I'll try that!

But without doing it this way - how would you actually prevent the object from going within the bounds?

You're asking how to prevent it without preventing it? :s

Isn't that like asking how to prevent intercourse with you already inside the girl?

You already failed a few steps back?

LO

LLL

rofl

Lol - I already have collision detection. I'm asking how to make it look like collision is happening.

By doing exactly what I just said. :P

Prevent it from entering the bounds by changing the velocity instead of the position.

so... Velocity = 0 o:

No

Set velocity to the distance between the two bounds.

...
    deltaVelocity.X = verticalWall.Value.BoundingBox.Right - this.Left;
...

That's how I do AABB collision between Tiles and Entities.

That would be whenever I hit an object and I'm moving left.

@James I saw your Minecraft Survival Video o:

@Moshe Have you considered not doing so? :P

Anyone in here have a good understanding of the MIT License?

Well, yeah, I know the license. I'm just curious how it works.

Am I allowed to add it to my closed source project?

@William Did that link help? o:

A bit yes. :P

3:23 AM

Lol - I'm not even focused on a license in my development process... at least not yet :P

Right, now I'm just fleshing out the good ideas from the bad - and trying to get core game-play down.

Oh, I'm just looking at what I need to do with this Lidgren thing I'm using.

Ah - it's a network library! o.o I have never done Network Programming before lol... is it hard?

Lidgren does simplify a bunch of things.

It's geared towards network protocols with lots of smaller packets.

Which is common in most games.

At least, in action games. :)

@WilliamMindWorXMariager Action Games FTW. Slow paced games can get on my nerves - but I can appreciate a good plot :)

Finally passes a level on SMB(Super Meat Boy) - Woot!

aaand - I'm going to go :(

Lol good bye everyone.

@CodeAssasssin For TFCraft?

5:00 AM

fixed that single issue, you were right @Kikaimaru

i had added something then changed it from const to public without realizing

that it would affect my serialization

yeah errors in content pipeline are not so good :)

well i fixed it, which is nice

i hate it that you can't rewrite anything from write step...

its so frustrating...

@JMRboosties oh yeah, thats nice :)

@Kikaimaru yea thats really annoying.

ok now i have movement down. i need to implement collisions

by the way, its possible to write content reloader, that will automaticaly reload your map for example into a game

but you probably dont need that right now, its kind of complex and for now you can just restart game :)

oh, did you read that wiki link i send you?

@JMRboosties wiki.themanaworld.org/index.php/…

but you would need to draw all collisions by yourself, if you set tile properties on tile you dont need that

5:10 AM

i did @Kikaimaru

tile-based collisions are pretty easy

i added a boolean to the layer element in the xml file for the map

if its a collision layer or not

so every time you move it checks if the tile you're moving to has a texture on one of the collidable layers

oh i see thats what you meant by layer element :)

yea

its a pretty good system imo

it just does a foreach on the layers and checks if its collidalbe, and if so checks if if it has a non null tile on that coordinate

if it does you're kicked out

rather, denied the movement

but i dont have any speed control right now

i need to slow it down

well its kind of wastefull to use ints to store boolean collision, and whats more have it loaded some texture, but whatever its probably nothing :)

can you change tile size of just one layer?

no you cant

well thats sad :)

5:24 AM

why would you wanna do that?

you could make collision layer two times smaller

@WilliamMindWorXMariager Asura is not that bad either

Asura?

ehm

was just playing asuras wrath, im kind of messed up :)

what is it called... :)

ASIRRA :)

i got same game 3 times in 5 reloads .)

6:21 AM

@Kikaimaru the collision layer still draws stuff

6:40 AM

@JMRboosties What? Why? what stuff? :)

like, buildings and stuff

instead of having two map objects, one drawn and one for collisons

i just combined the two

a layer with collidable objects like houses and stuff cant be passed through due to an xml attribute

its working great now.

what i need to do is implement a movement speed
