But I still need to make an A* pathfinding system like how I described it. Maybe a bit like Half-Life's nodegraph system. Good thing they have it in the SDK.

I could use Renderware but I've done a lot of progress on my engine already. I don't know if it'll be a waste if I quit with it. But on other hand I can use it for my Series S games since Unity is dying. So Renderware works as it should now? Then I can use that.

Hello. The Grendel Engine (In A Creation) has had a lot of development done with the first NPC programmed in. Now it should follow a path. I'm currently stuck in thoughts about my engine's pathfinding which is gonna be an A* system. My plan is to use a connection system for optimization but are stuck on how to implement it. The nodes are scattered around the level and are connected via links to visible and nearby nodes and it creates a path for the NPC to follow from the nearest node (From the NPC) to the point that is nearest the end node. Then when close enough the NPC moves straight to the point (Instead of the end node's own position). This tutorial gave me some insight on it but I need to convert it to use D3DXVECTOR3 coordinates instead. Anyone has anything to say to help me here? It's needed for now. Meerjel01

My thoughts was that I would tell people to wait with the pirating until it's no longer payable and hope people would respect it or try make it a law and call free copies of the game stealing. An older idea was to put up a high enough donation pool to release the game and still get payed for making it. I could release it for free but I don't know if I'll get rewarded enough for it.

The game, In A Creation, is still in my head and will continue development even if my Xbox Series S games are of higher priority. Currently in question how to implement the A* system into the engine in an optimized way (Tho I still have an idea for how) and are about to add my first physics object into the game to check if it'll lag. I shouldn't use this topic anymore since it was a question if homebrew games can sell originally. But I'll reveal as little as possible anyway!

From my character collider code. Take a newDirection vector variable and use this for your triangles. (AABB character vs world triangle collision) D3DXVECTOR3 TriangleCollision(CTri triangle, D3DXVECTOR3 dir, D3DXVECTOR3 lastPos, D3DXVECTOR3 currentPos) { D3DXVECTOR3 vNorm = GetNormal(triangle); colliding = false; triIsGround = false; triIsCeiling = false; triIsWall = false; if(CPyhsics::TriangleIntersectAABB(boundingBox, triangle)) { colliding = true; triIsGround = CPyhsics::GetGrounded(vNorm, D3DXVECTOR3(0, -1, 0), 0.5); triIsCeiling = CPyhsics::GetGrounded(vNorm, D3DXVECTOR3(0, 1, 0), 0.5); triIsWall = !triIsGround && !triIsCeiling; if(triIsGround) grounded = true; D3DXVECTOR3 tempV = NegateVector(vNorm); tempV *= D3DXVec3Length(&MultiplyVector(dir, vNorm)); D3DXVECTOR3 wallDir = dir - tempV; D3DXVECTOR3 closestPtn = CPyhsics::GetClosestPointOnTriangle(currentPos, triangle); if(currentPos.y > closestPtn.y) return dir; D3DXVECTOR3 newPos = lastPos + wallDir; D3DXVECTOR3 newDir = newPos - lastPos; return newDir; } return dir; } Call it without using + or - btw.

Know triangle collision? No? Here then! static bool AABBTriangleSAT (D3DXVECTOR3 testAxis, Caabb box, D3DXVECTOR3 v0, D3DXVECTOR3 v1, D3DXVECTOR3 v2) { float p0, p1, p2; p0 = D3DXVec3Dot(&v0, &testAxis); p1 = D3DXVec3Dot(&v1, &testAxis); p2 = D3DXVec3Dot(&v2, &testAxis); float r = box.extents.x * abs(D3DXVec3Dot(&u0, &testAxis)) + box.extents.y * abs(D3DXVec3Dot(&u1, &testAxis)) + box.extents.z * abs(D3DXVec3Dot(&u2, &testAxis)); return max(-largest(p0, p1, p2), smallest(p0, p1, p2)) > r; } static bool TriangleIntersectAABB(Caabb box, CTri triangle) { D3DXVECTOR3 v0 = triangle.p0; D3DXVECTOR3 v1 = triangle.p1; D3DXVECTOR3 v2 = triangle.p2; v0 -= box.center; v1 -= box.center; v2 -= box.center; D3DXVECTOR3 f0 = v1 - v0; D3DXVECTOR3 f1 = v2 - v1; D3DXVECTOR3 f2 = v0 - v2; D3DXVECTOR3 ax_u0_f0, ax_u0_f1, ax_u0_f2; D3DXVECTOR3 ax_u1_f0, ax_u1_f1, ax_u1_f2; D3DXVECTOR3 ax_u2_f0, ax_u2_f1, ax_u2_f2; D3DXVec3Cross(&ax_u0_f0, &u0, &f0); D3DXVec3Cross(&ax_u0_f1, &u0, &f1); D3DXVec3Cross(&ax_u0_f2, &u0, &f2); D3DXVec3Cross(&ax_u1_f0, &u1, &f0); D3DXVec3Cross(&ax_u1_f1, &u1, &f1); D3DXVec3Cross(&ax_u1_f2, &u1, &f2); D3DXVec3Cross(&ax_u2_f0, &u2, &f0); D3DXVec3Cross(&ax_u2_f1, &u2, &f1); D3DXVec3Cross(&ax_u2_f2, &u2, &f2); if(AABBTriangleSAT(ax_u0_f0, box, v0, v1, v2) || AABBTriangleSAT(ax_u0_f1, box, v0, v1, v2) || AABBTriangleSAT(ax_u0_f2, box, v0, v1, v2) || AABBTriangleSAT(ax_u1_f0, box, v0, v1, v2) || AABBTriangleSAT(ax_u1_f1, box, v0, v1, v2) || AABBTriangleSAT(ax_u1_f2, box, v0, v1, v2) || AABBTriangleSAT(ax_u2_f0, box, v0, v1, v2) || AABBTriangleSAT(ax_u2_f1, box, v0, v1, v2) || AABBTriangleSAT(ax_u2_f2, box, v0, v1, v2)) { return false; } D3DXVECTOR3 triNormal = D3DXVECTOR3(0,0,0); D3DXVec3Cross(&triNormal, &f0, &f1); if(AABBTriangleSAT(u0, box, v0, v1, v2) || AABBTriangleSAT(u1, box, v0, v1, v2) || AABBTriangleSAT(u2, box, v0, v1, v2)) { return false; } if(AABBTriangleSAT(triNormal, box, v0, v1, v2)) return false; return true; } Collision response soon..

Well I can't teach by words but I can give code I guess. static bool PointIntersectAABB(D3DXVECTOR3 point, Caabb box) { return (point.x > box.center.x - box.extents.x && point.x < box.center.x + box.extents.x && point.y > box.center.y - box.extents.y && point.y < box.center.y + box.extents.y && point.z > box.center.z - box.extents.z && point.z < box.center.z + box.extents.z); } static bool AABBIntersectAABB(Caabb box1, Caabb box2) { return (abs(box1.center.x - box2.center.x) < (box1.extents.x + box2.extents.x) && abs(box1.center.y - box2.center.y) < (box1.extents.y + box2.extents.y) && abs(box1.center.z - box2.center.z) < (box1.extents.z + box2.extents.z)); } These are from my Physics functions class.

Thank you. Currently I want to implement A* pathfinding to the engine but aren't that lucky with knowing how. Also have you played the demo?

To be honest I like it when the Xbox was weak enough for people to use their imagination for their work for it. Newer generations are losing their souls.

A question for the next entry. 2D sprites in 3D or skinned 3D models? I can 2D in 3D well but Skinned models is needed to be taught about someday.

Updated it with some lighting In A Creation.zip Just felt like completing this a bit.

I'm not sure if I can help unless it's simple code. I'm also busy with my own projects so the chance is even smaller. Have you seen the website I've linked to in my XTL tutorial series?

Here it is In A Creation.zip Not much to look at but it's a lot of progress since the start. It's 3rd person with no camera collision (Yet) and has simple physics. X to take a screenshot. Y to do a pose. Both triggers and black button to reset.

I can try get a demo up today but I will also try not to show too much of my early progress to make people wait too long.

I might be too proud of this. Maybe because I haven't gotten this far before?

It's actually a video

W.I.P preview of the game incoming! Here it is. https://drive.google.com/file/d/1HtBXQ2tnf3loRDc_599Kn3AFRS-IvP3b/view?usp=share_link

It's okay for me even if I get little out of this cause I'm not planning on staying in the game industry my whole career. I want to be a cartoonist artist and make animations and comics. I only do games cause I feel like I need to finish my plans. Sorta getting it over with.

Yes mah man! Though how should I make it so people doesn't share the files around? I feel like I need the earnings for my work and this community is a bit of a "Take and send" group.

Can I make money out of making and selling original games for the console? The games will have original assets and settings to avoid copyright and will be sold with decent prices so I thought it was a good idea. But is it legal to do it? Meerjel01

I don't know if the array method I posted will work anymore cause of recent discoveries. So let's say that you need to call all texture files for the map from a file by text and put them in an array of DirectX textures. I'm sorry if I disappointed anyone but hopefully it's understandable. Still, I've did some progress. I've figured how to make a sprite system. Haven't tested animation yet but will eventually do that now when I've gotten this engine running properly.

Small reminder when taking info from a file and putting them in variables. Give the variables some content before doing ">>" on them

Alright. eBay.
