[How to create a "rope" between two positions?]

I like the result of a 3d line, I just need to make a few adjustments, it's in the wrong position when it's descending.

[How to create a "rope" between two positions?]

I'm creating a zipline resource, and I'd like to know how to create a rope between two points, any ideas? I remember seeing a resource for a gas station, where there was a hose that changed size dynamically.
 

Resource: zipline 

I don't know if it's a smart option, but I can make some models with fixed sizes, 10 meters, 5 meters, 2 meters and 1 meter.

Depending on the distance, I calculate how many objects I need to create and create them in sequence.

Example 23 meters away, 2x10m + 2m + 1m.

What do you think?

[how to make the player look at an object?]

Very good animation, thanks!

 

[how to make the player look at an object?]

I'm making a resource zipline and I'd like to make the player look in the right direction when he starts moving, any idea how to do that?

I would also like to know if there is an animation that looks like the player is using a zipline.

[[Help] Making a radar from scratch]

 

I have the following problem, I need the blip to be stuck to the edge of the radar.

Spoiler

Spoiler

function drawBlip(posX, posY, size, texture, color, visibleDistance)
	-- @description: Draw a blip
	-- @implementation version: Alpha

	-- @param: {posX} (Float) Blip X position.
	-- @param: {posY} (Float) Blip Y position.
	-- @param: {size} (Int) Blip size.
	-- @param: {texture} (Texture) Blip texture.
	-- @param: {color} (Color) Blip color.
	-- @param: {visibleDistance} (Float) Maximum distance the blip should be rendered.

	-- @return: No return.
	-- @example: createCustomBlip(50,0, 10, nil, tocolor(0,255,0,255), 300)

	local distance = getDistanceBetweenPoints2D(posX, posY, playerPosition.x, playerPosition.y)
	
	--Avoid rendering blips that are not in the player's view.
	if distance > visibleDistance then return end 

	local radarCenter = getRadarCenter()
	local radarFix = 2.5
	local blipDistance = Vector2((posX - playerPosition.x), (posY - playerPosition.y))
	local x,y = ( blipDistance.x / radarFix), ( blipDistance.y / radarFix ) 
	local position = Vector2(
		radarCenter.x - (size/2) + x,
		radarCenter.y - (size/2) - y
	)

	dxDrawImage(position.x, position.y, size, size, texture, camRot, -x, y, color)
end

I know I need to do some sort of math.clump, to prevent the blip from rendering outside of the minimap's border
 

function math.clamp( _in, low, high )
	return math.min( math.max( _in, low ), high )
end

I performed some tests and almost succeeded, however, I'm not sure if the way I implemented to position the blips was the most efficient.


How does the radar work?
It is based on shader_hud_mask, and it is rendered like this:
 

Spoiler

local radar = {
	currentShape = "circle",
	zoom = 8,
	arrowSize = 16,
}

radar.square = {}
radar.square.size = Vector2(300, 200)
radar.square.position = Vector2(10, SH - radar.square.size.y - 10)

radar.circle = {}
radar.circle.size = Vector2(300, 300)
radar.circle.position = Vector2(10, SH - radar.circle.size.y - 10)

function drawMinimap()
	playerPosition = Vector2(getElementPosition(localPlayer))
	_,_,camRot = getElementRotation(getCamera())
	_,_,playerRot = getElementRotation(localPlayer)

	-- Transform world x,y into -0.5 to 0.5
	local x,y = playerPosition.x, playerPosition.y
	x = ( x ) / 6000
	y = ( y ) / -6000
	dxSetShaderValue( SHADER_MASK, "gUVPosition", x,y )

	local radarCenter = getRadarCenter()

	if radar.currentShape == "circle" then 
		dxSetShaderValue( SHADER_MASK, "gUVScale", 1/radar.zoom, 1/radar.zoom )

		dxDrawImage( radar.circle.position.x, radar.circle.position.y, radar.circle.size.x, radar.circle.size.y, SHADER_MASK, camRot,0,0)
		drawBlips()
		dxDrawImage(radar.circle.position.x, radar.circle.position.y, radar.circle.size.x, radar.circle.size.y, TEXTURE_OUTLINE_CIRCLE)
		dxDrawImage(radarCenter.x - (radar.arrowSize/2), radarCenter.y - (radar.arrowSize/2), radar.arrowSize, radar.arrowSize, TEXTURE_ARROW, camRot - playerRot)
	else -- Square
		dxSetShaderValue( SHADER_MASK, "gUVScale", 1/radar.zoom, 0.667/radar.zoom )
		dxSetShaderValue( SHADER_MASK, "gUVRotAngle", math.rad(-camRot) )

		dxDrawImage(radar.square.position.x, radar.square.position.y, radar.square.size.x, radar.square.size.y, SHADER_MASK, 0,0,0)
		drawBlips()
		dxDrawImage(radar.square.position.x, radar.square.position.y, radar.square.size.x, radar.square.size.y, TEXTURE_OUTLINE_SQUARE)
		dxDrawImage(radarCenter.x - (radar.arrowSize/2), radarCenter.y - (radar.arrowSize/2), radar.arrowSize, radar.arrowSize, TEXTURE_ARROW, camRot - playerRot)
	end
end

 

Any idea how I can do this?

[Can I make the native radar square?]

I just changed the texture of the radar outline, radardisc.

[Why does dxDrawText use end position and not width and hight?]

I solved the problem by doing this:
 

function dxNewDrawText(...)
    arg = {...}
    arg[4] = arg[2] + arg[4]
    arg[5] = arg[3] + arg[5]
    dxDrawText(unpack(arg))
end

But I would like to understand the reason to use end position.

[[Question] Physics not available?]

All function related to physics are unavailable yet right?

 

local terrainData = {
  3,3,3,3,
  3,0,0,3,
  3,0,0,3,
  3,3,3,3,
}
local terrainShape = physicsCreateShape(physics, "heightfieldterrain", 4,4, terrainData)
local terrain = physicsCreateStaticCollision(terrainShape)
physicsSetProperties(terrain, "position", 0,0,5)
physicsSetProperties(terrain, "scale", 5,5,1) -- in terrain, sets mesh density, now mesh has size 20x20units, one vertex every 5 units

With this script plus shader it would be possible to create custom terrains, right?

[check jump]

local tick = getTickCount()
local delay = 150 -- ms
local jump = false

addEventHandler("onClientRender", root, function()
    if getTickCount() - tick > delay then
        
        if getPedControlState(localPlayer, "jump") and not jump then
            outputChatBox("jump")
            jump = true
        elseif not getPedControlState(localPlayer, "jump") and jump then
            jump = false
        end

        tick = getTickCount()
    end
end)

So you can detect, regardless of the key that the player presses.

Note: Dynamic objects do not automatically have physics applied to them. Use setElementVelocity(object, 0, 0, 0) to fix this.

[How to remove shadows from vehicles?]

local function removeShadow(vehicle)

    local shader = dxCreateShader("files/replace.fx", 0, 0, false, "vehicle")
    local texture = dxCreateTexture("files/remove.png")

    dxSetShaderValue(shader, "gTexture", texture)
    engineApplyShaderToWorldTexture(shader, "shad_car", vehicle)
end

and

local function removeShadow(vehicle)

    local shader = dxCreateShader("files/replace.fx", 0, 0, false)
    local texture = dxCreateTexture("files/remove.png")

    dxSetShaderValue(shader, "gTexture", texture)
    engineApplyShaderToWorldTexture(shader, "shad_car", localPlayer)
end

Neither worked, I want to remove the shadow of a specific vehicle, not all.
The texture name of the shadow I know is "shad_car"

And this replace shader works because I used it in other things, I just don't understand why it didn't work for the shade.

Any solution?

‎Esta é uma espécie de limitação GTA:SA. Existem mods (para GTA:SA) que podem remover essa limitação, mas sem mods eu não acho que seja possível no MTA.‎

You can create a ped and warp it in the vehicle and use setPedAnalogControlState to turn to the last known direction by the player BUT warpPedIntoVehicle only works with client created peds and vehicles (those are not seen by the other players).
Sooo it seems impossible.

‎Você poderia escrever isso ‎‎aqui‎‎ como um problema, mas eu não sei se eles vão se importar com isso. ‎

I think the easiest thing would be to add a ped with alpha 0 and remove it when the player enters.
