Need Help CODING a hitbox!

IndigantSitting14

Hi! I'm trying to make a platformer but I don't know how to CODE a hitbox for collisions. Can you please help me? Thanks.

Make a new costume in your player's sprite. Draw a Square for how big you want your character's hitbox to be.

Now, make sure when you're running the more complex parts of your script to switch the player costume to the hitbox one. Then, after collision has been detected and satisfied, switch it back.

For coding a hitbox, are you trying to make a pen platformer? In this case, you would need to store the player x and y, and then you can create a hitbox by drawing a square that fits your requirements.

But for the code, for a pen player on pen grounds, you would need to figure out which x and y velocity is changing, and check that side of the hitbox.
like if your player is moving right, and there is a wall, you need to check the right hitbox wall. you can calculate if the hitbox line is over the wall line. This would then need to push the player out of the wall. Now just do this every tick. It sounds complex, so if you need help coding it up I'm here.

Then why would you want to code a hitbox? What are you making?

Hello! What are you using the hitbox for?

Can you not use the

sensing block?

I'm using the hitbox for collisions so that the player can detect that they have hit a wall then the player should stop once he has touched a wall.

I'm trying to make a simple platformer, but with good collisions. So I want to use a hitbox for that, but I don't know how to code it.

Just make a new sprite called “Player Hitbox” or something like that, and draw a square for how big you want the hitbox to be. Make the hitbox sprite always have a ghost effect of 100 (invisible but can still have collision), and make the sprite always go to the normal player sprite in a forever loop.

Every time collision is detected with the <if touching (Player)> block, replace the input with your new sprite. <if touching (Player Hitbox)>

So, you want to code up a hitbox. When you said code, I thought you meant not using the costume editor.

I would watch a tutorial for platformers. Griffpatch has some. https://www.youtube.com/watch?v=D16hTnDGweo (episode 1)

me and my friend Toxiclandsgdash2-2 are racing to publish a platformer game frist and i cant figure hit boxes i need help pls

bsteichman

you could use a my block and a costume divided into 4 colors that don't appear in any other part of your project, if you want to know which edge of the player the hitbox touched

\ red /
\ /
blu\ / yellow
/ \
/ \
/ green \

then in your level sprite (floors n walls) you can do

and in your player sprite:

make sure to make the block “run without screen refresh” then it will try to complete all of this in one frame, so it won't show the hitbox to the user.

I'm Trying to make a boss but I don't know how to do the hitbox to damage the player

vdiu

Make a hitbox which is a square with a outline of 0.05 and no inside, and then use

and then for the visible sprite

To get go to player go into another sprite and select go to player then drag it into your player sprite. If you want to animate use this instead

and for the actual animation

etc etc.
