Camera always moves upwards? [by clonman]

Hello,
I haven't used GameStudio A8 in a long time and already I have a problem.
I created a small test example and assigned the pre-made script "t_player" to the model.

My main.c script looks like this:

///////////////////////////////
#include <acknex.h>
#include <default.c>
#include <mtlFX.c>
///////////////////////////////

#include <t_player.c>
#include <t_enemies.c>
#include <t_weapons.c>
///////////////////////////////

function main()
{

level_load("my_new_game.WMB");
}

If I start the example now, the following happens: The camera simply moves endlessly upwards?

No joystick or gamepad is connected.

Could someone perhaps tell me why this is happening and how I can stop it?

( GameStudio Commercial 8.47 / WED V 6.961 / SED version: 8.10.3 )

Thank you.

Clonman

Re: brokerCommand PLOT_HLINE parameters [by M_D]

Well, script is running without errors. But dont get plots on mt4 chart.
Can someone tell me how to return a brokercommand value (check if !=0)?
on the mt4 terminal there are no related messages in Experts or Journal tab.

Zorro manual "MT4/5 Bridge" gives advise on how to get a return, i have read it ... but not really understood. And seems to me like explaination for "own generated broker commands".
Not my case, already predefined. so how to proceed?

Re: brokerCommand PLOT_HLINE parameters [by M_D]

made the changes accordingly ...

Code

       var BreakEvenLongTrigger, LosingLongLevel;

       BreakEvenLongTrigger = TradePriceOpen + Range * 0.5;
       LosingLongLevel = TradePriceOpen - Range * 0.4;

        var hconfig_1[5];
	hconfig_1[0] = 0; // always 0
	hconfig_1[1] = BreakEvenLongTrigger; // price position
	hconfig_1[2] = GREEN; // line color
	hconfig_1[3] = 1; // line width
	hconfig_1[4] = LINE; // line style
	
	var hconfig_2[5];
	hconfig_2[0] = 0; // always 0
	hconfig_2[1] = LosingLongLevel; // price position
	hconfig_2[2] = ORANGE; // line color
	hconfig_2[3] = 1; // line width
	hconfig_2[4] = LINE; // line style

        brokerCommand(PLOT_HLINE, hconfig_1);
	brokerCommand(PLOT_HLINE, hconfig_2);

no compiler errors so far ... Thank you.
Testing now and will check if plots appear on mt4 chart ...

Re: brokerCommand PLOT_HLINE parameters [by AndrewAMD]

brokerCommand takes only two parameters. In your case:
brokerCommand (int Command, var* Parameters)

For PLOT_HLINE, it specifically says that the second parameter is var[5].

So in your script, you can do something like this:

Code

var hconfig[5];
hconfig[0] = 0; // always 0
hconfig[1] = 0; // price position
hconfig[2] = 0; // line color
hconfig[3] = 0; // line width
hconfig[4] = 0; // line style
brokerCommand(PLOT_HLINE, hconfig);

brokerCommand PLOT_HLINE parameters [by M_D]

Hi all,

need a hand regarding the brokerCommand PLOT_HLINE. Im using MT4 bridge and want to plot 2 pricelevels on mt4 chart.
manual says:

PLOT_HLINE | var[5] | Place a horizontal line at a given price in the chart window of the broker platform. 5 parameters are used: P[0] = always 0; P[1] = price position; P[2] = line color; P[3] = line width; P[4] = line style. Return the identfier number of the line.

so related part of my script looks like following:

Code

                BreakEvenLongTrigger = TradePriceOpen + Range * 0.5;
		LosingLongLevel = TradePriceOpen - Range * 0.4;

                brokerCommand(PLOT_HLINE,0,BreakEvenLongTrigger,GREEN,1,1);
		brokerCommand(PLOT_HLINE,0,LosingLongLevel,ORANGE,1,1);

those are placed within a tmf. if i try run with TRADE on mt4 demo account, zorro compiler gives following error:

brokerCommand(): wrong number of parameters
< brokerCommand(PLOT_HLINE,0,BreakEvenLongTrigger,GREEN,1,1);
>.

I could not find any further documentation or any examples on how the parameters have to be set. Any advice would be highly appreciated. (Zorro S 2.70)
rest of my script is running fine so far ...

Thanks in advance

M_D
