Shoot Bullets to player coordinate

[Emral]

'kay so... What I THINK is happening is that your bullet isn't configured to move opposite to its direction value somehow? Try to add the following bit of code to spawnAtDirection:

if directionVector.x ~= 0 then
n.direction = math.sign(directionVector.x)
end

You need to put this section before setting speedX, because setting direction afterwards does some weird stuff to speed I don't quite understand.
If that trick doesn't work... then I'm not sure.

Idk what about the frame... But let's move on something else... How would I make a custom block but it's a slope... Without replace a available one... Also, how would I make a one-way block?

P/s: How do I check for bumped block too?

[Emral]

Bumping routes through the onBlockHit function

function onBlockHit(eventObj, hitBlockObject, fromUpperSide, playerOrNil)
...
end

Use like onNPCHarm and onNPCKill.
For the block property settings, lua is required at the moment. You can manipulate them with Block.config

Examples:
Block.config[751].bumpable = true
Block.config[752].semisolid = true
Block.config[753].floorslope = 1 (or -1, depending on direction)

There's also ceilingslope (works same as floorslope), passthrough (nonsolid), pswitchable, sizeable, and lava (all booleans), as well as frames (int) and the 5 darkness related fields that also exist for NPCs and BGOs (lightoffsetx, lightoffsety, lightradius, lightbrightness, lightcolor)

Awesome... So does this work with 32x64 slope? Or I have to make 2 different pieces? Also can I do the uppersolid or bottomsolid or leftsolid... lol I'm dumb... Or should I use NPC...?

[Emral]

Bottomsolid and sidesolid are not supported by SMBX. You gotta do some weird hacks to get those working, and even then it's hard to make them work for players AND npcs.
Blocks resize automatically based on their image size. The slope flags just define the orientation of the collision triangle (which is then stretched to fit the image size).

Lol that's no big deal... I believe lua can implement pretty much thing... In the future, it will be possible :3. Thank for helping

How do I check for block collision? I use collision up/down/left/right but my custom npc stuck at ceiling slope (btw my custom is no gravity and speed = 0 with my old spawnAtDirection function)...

What are you trying to do? If you're trying to reflect it, look at rebound.lua in the scripts/npcs folder.That file is used by diagonal podoboos and boo snakes. For proper reflections you have to work with raycasts. If you're just trying to kill it or whatnot, the collidesBlockBottom/Top/Left/Right flags should work as long as the NPC has block collision enabled.

ok nvm... This is solved... But how can I make a custom powerup without replace or fix the current power...?

[Emral]

You must replace an existing powerup at the moment. If we had the ability to add more yet, there would be some in basegame.

i think this might be good for tank levels
like player control a tank and shoot using mouse pointer to aim
